| 2 | Magnetic properties and large magnetocaloric effects in amorphous Gd-Al-Fe alloys for magnetic refrigeration显示文摘A series of the amorphous Gd75-55Al25-5Fe0-40 alloy ribbons were prepared by melt spinning.The structure,magnetic properties and magnetocaloric effect(MCE) of these alloys were investigated.The prepared samples have shown the characteristics of a second-order phase transition with zero hysteresis loss and the Tc can be tuned by changing the Fe contents.For the different compositions,the magnetic entropy change(--Sm) for a field change of 0-5 T reached a maximum value of 7.14 J kg-1 K-1 in the Gd70Al20Fe10 alloy near its Curie temperature(Tc) of 149 K.The non-linear composition dependence of(-ΔSm) could be caused by the competitions between Fe-Fe,Fe-Gd and Gd-Gd interactions.The refrigeration capacity(RC) values of these alloys are about 532-780 J/kg under a magnetic field change of 0-5 T.The results indicate that amorphous GdFeAl alloys can be considered as ideal candidates for a magnetic refrigerant in the temperature range of 104-222 K. | ZHENG ZhiGang ZHONG XiChun SU KunPeng YU HongYa LIU ZhongWu ZENG DeCheng | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，7： | 8 |
| 3 | Thermal Growth and Nanomagnetism of the Quasi-one Dimensional Iron Oxide显示文摘Quasi-one dimensional iron oxide nanowires with flat needle shape were synthesized on the iron powders by a rather simple catalyst-free thermal oxidation process in ambient atmosphere. The characterization by field emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Raman and high-resolution transmission electron microscopy (HRTEM) revealed that these nanostructures are single crystalline α-Fe2O3. The various dimensions with 40-170 nm in width and 1-8 μm in length were obtained by tuning the growth temperature from 280 to 480℃. A surface diffusion mechanism was proposed to account for the growth of quasi-one dimensional nanostructure. The typical α-Fe2O3 nanowires synthesized at 430℃ had a reduced Morin temperature TM of 131 K in comparison with their bulk counterpart. The coercivitis Hc of these nanowires are 321 and 65 Oe at 5 and 300 K, respectively. The temperature of synthesis also has important effects on the magnetic properties of these nanowires. | Minglong Zhong Zhongwu Liu Xichun Zhong Hongya Yu Dechang Zeng | 2011 | Journal of Materials Science & Technology2011，27，11： | 5 |
| 4 | Microstructure improvement related coercivity enhancement for sintered NdFeB magnets after optimized additional heat treatment显示文摘The micro structure, especially the Nd-rich phase and the grain boundary, in sintered NdFeB magnets plays an important role in magnetic reversal and coercivity mechanism. To better understand the effects of the microstructure on the coercivity, we investigated the microstructure and properties improvements of a commercial sintered NdFeB magnet after optimized additional heat treatment. The coercivity is enhanced from 1399 to 1560 kA/m. This enhancement has been explained in terms of the evolution of the grain boundary structure, and the formation of continuous thin layers of Nd-rich phase is important for high coercivity. The micromagnetic simulation together with the numerical analysis based on the nucleation model suggest that the reversed magnetic domains nucleate mainly at the interface of multijunctions of Nd_2 Fe_(14)B grains with high stray fields during the demagnetization process. Both improved anisotropy fields at grain boundaries and reduced stray fields at multi-junction Nd-rich phases contribute to the coercivity enhancement. This work has importance in understanding the crucial micro structure parameters and enhancing the obtainable properties for sintered NdFeB magnets. | Qing Zhou Wei Li Yuan Hong Lizhong Zhao Xichun Zhong Hongya Yu Lili Huang Zhongwu Liu | 2018 | Journal of Rare Earths2018，36，4： | 4 |
| 5 | Magnetic properties and magnetocaloric effects in amorphous and crystalline Gd_(55)Co_(35)Ni_(10) ribbons显示文摘The magnetic properties and magnetocaloric effects of amorphous and crystalline Gd55Co35Ni10 ribbons are investigated.A main phase with a Ho 12 Co 7-type monoclinic structure(space group P21/c) and a minor phase with a Ho4Co3-type hexagonal structure(space group P63/m) are obtained for crystalline ribbon after annealing.The amorphous ribbons order ferromagnetically and undergo a second-order transition at 192 K.For crystalline Gd55Co35Ni10 ribbons,two magnetic phase transitions occur at 158 and 214 K,respectively.The peak value of-△SM under a field change of 0-5 T is 6.5 J/kg K at 192 K for amorphous Gd55Co35Ni10 ribbons.A relatively large magnetic entropy change(~5.0 J/kg K) under a field change of 0-5 T for the crystalline Gd55Co35Ni10 ribbons is obtained in the temperature interval range of 154-214 K.The large platform of magnetic entropy change and the negligible thermal/magnetic hysteresis loss mean the crystalline Gd55Co35Ni10 compound can satisfy the requirement of the Ericsson-type refrigerator working in the temperature range from 154K to 214K. | ZHONG XiChun TANG PengFei GAO BeiBei MIN JiXiong LIU ZhongWu ZHENG ZhiGang ZENG DeChang YU HongYa QIU WanQi | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，6： | 3 |
| 6 | Structure and magneto-electrical properties of Fe-C films prepared by magnetron sputtering显示文摘Fe-doped amorphous Fe x C 1 x granular films were prepared on n-Si(100) substrates by d.c.magnetron sputtering.The structural properties of Fe x C 1 x films were investigated by X-ray diffraction(XRD),atomic force microscope(AFM) and Raman spectroscopy.The results show that the iron and carbon of as-deposited films are in amorphous state,and the Fe x C 1 x films are diamond-like carbon(DLC) films.After doping iron into the DLC films,a smooth surface morphology of the Fe x C 1 x films has been obtained with the surface roughness Ra of about 0.231 nm for x=18at%.The Fe x C 1 x films have good soft magnetic properties with the coercivity of approximately 20 Oe.A high positive magnetoresistance(MR) up to 93% with x=1at% was observed in a Fe x C 1 x granular film at 300 K.The resistance characteristic of Fe-C films is changed at about 230 K and the positive MR effect can be understood by the p-n heterojunction theory. | MA Lei LIU ZhongWu ZENG DeChang YU HongYa ZHONG XiaPing ZHANG XiaoZhong | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，9： | 3 |
| 7 | Microstructure of pre-sintered permanent magnetic strontium ferrite powder显示文摘The microstructure and characteristics of pre-sintered strontium ferrite powder were investigated by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The present study shows that the pre-sintered strontium ferrite powder is provided with a certain particle size distribution, which results in high-density magnets. The strontium ferrite particle has a laminar hexagonal structure with a size similar to ferrite single domain. Ferric oxide phase due to an incomplete solid phase reaction in the first sintering is discovered, which will deteriorate the magnetic properties of ferrite magnet. In addition, the waste ferrite magnets with needle shape arranging along C axis in good order into the powders are found, which have no negative effects on finished product quality. | YU Hongya LIU Zhengyi ZENG Dechang | 2006 | Rare Metals2006，25，z1： | 2 |
| 8 | Simultaneous enhancement of coercivity and electric resistivity of Nd-Fe-B magnets by Pr-Tb-Al-Cu synergistic grain boundary diffusion toward high-temperature motor rotors显示文摘To high-power permanent magnetic motors,it is critical for Nd-Fe-B magnets to maintain the desirable coercivity at high-temperature operating conditions.To address this,two approaches have been proven effective:(1)enhancing the room temperature coercivity;(2)reducing the eddy current loss.However,these two items are difficult to be simultaneously achieved.Here,the grain boundary diffusion(GBD)of the Pr-Tb-Al-Cu-based source is applied to enhance the coercivity and electric resistivity at room temperature from 1101 kA m-1 and 2.13×10–6Ωm to 1917 kA m-1 and 2.60×10–6Ωm,and those at 120°C from 384 kA m-1 and 4.31×10–6Ωm to 783 kA m-1 and 4.86×10–6Ωm,respectively.Such optimization is ascribed to the improved formation depth of Tb-rich 2:14:1 shells with large magnetocrystalline anisotropy and the increased intergranular Pr-based oxides with high electric resistivity,induced by the coordination effects of Tb and Pr,as proven by the atomic-scale observations and the first principles calculations.It thus results in the simultaneously improved output power and energy efficiency of the motor because of the combination of magnetic thermal stability enhancement and eddy current loss reduction,as theoretically confirmed by electromagnetic simulation. | Jiayi He Jinwen Hu Bang Zhou Haoyang Jia Xiaolian Liu Zhenhua Zhang Lin Wen Lizhong Zhao Hongya Yu Xichun Zhong Xuefeng Zhang Zhongwu Liu | 2023 | Journal of Materials Science & Technology2023，，23： | 1 |
| 9 | Effects of grain boundary diffusion process on magnetic properties enhancement and microstructure evolution of hot-deformed Nd-Fe-B magnets显示文摘Grain boundary diffusion(GBD)process is an important approach for producing Nd-Fe-B magnets with high coercivity and high thermal stability.The GBD for hot-deformed Nd-Fe-B magnets with nanocrystalline micro structure is more complicated compared to sintered magnets.Here,we investigated the effects of different GBD methods,i.e.,intergranular addition(in-situ GBD 1#),in-situ GBD from magnet surface during hot pressing and hot deformation(in-situ GBD 2#),and conventional GBD,on the magnetic properties and microstructure of hot deformed magnets.After the treatment by these three GBD approaches using 2 wt%Pr_(40)Tb_(30)Cu_(30)diffusion source,the coercivity of the hot-deformed magnet increases from 1281 to 1567,1412 and 2022 kA/m,respectively.The coercivity enhancement is attributed to the formation of local(Nd,Tb)2Fe14B phase with stro ng magnetic anisotropy.Reduced grain orientation is found in both in-situ GBD 1#and conventional GBD treated samples mainly due to the local stress state variation and the rotation of platelet grains.Interestingly,the in-situ GBD 2#processed sample has a high orientation at diffusion surface,which may be caused by the modified surface state of the magnet by the diffusion source.Compared with the in-situ GBD processes,the conventional GBD exhibits a higher utilization efficiency of Tb.Since the in-situ GBD is effective to treat thick hot-deformed magnets,further effort should be aimed at enhancing its diffusion efficiency. | Jiayi He Yukun Liu Zhigao Yu Jiali Cao Hongya Yu Zhongwu Liu | 2023 | Journal of Rare Earths2023，41，5： | 1 |
| 10 | TEM observation of sintered permanent magnetic strontium ferrite显示文摘Sintered permanent magnetic strontium ferrites were studied using transmission electron microscopy to investigate the microstructure morphology and its correlation with the magnetic properties. The present study shows that the microstructure of sintered permanent magnetic strontium ferrites is an important parameter in determining their magnetic properties. The microstructure morphology in low-performance ferrite magnet is obviously different from high-performance one. The magnetic properties of sintered permanent strontium ferrite depend strongly on the orientation degree of strong magnetic crystals. The presence of ferric oxide phase in ferrite magnet can deteriorate the magnetic properties. Moreover, proper quantities of crystal defects are beneficial to high coercive force due to the fixing of magnetic domain. | YU Hongya LIU Zhengyi ZENG Dechang | 2006 | Rare Metals2006，25，z1： | 1 |

| 13 | Development of cost-effective nanocrystalline multi-component(Ce,La,Y)-Fe-B permanent magnetic alloys containing no critical rare earth elements of Dy,Tb,Pr and Nd显示文摘Here we first report the fully abundant rare earth(RE)-based nanocrystalline multi-component(Ce,La,Y)-Fe-B alloys containing no critical RE elements of Nd,Pr,Dy,and Tb by melt-spinning technique.The roles of La and Y substitutions for Ce have been fully understood.La plays a positive role on both thermal stability and room-temperature(RT)magnetic properties.The enhanced coercivity H_(cj)by partial substitution of La is attributed to the increases of anisotropy field H_A and the formation of continuously distributed grain boundaries resulting from the suppre s sion of CeFe_(2)phase.Although Y substitution is not benefit for H_(cj),both remanent polarization J_r and thermal stability have been effectively improved since Y_(2)Fe_(14)B shows relatively high saturation magnetization M_s and a positive temperature coefficient of HA over a certain temperature range.In addition,RE element segregation has been confirmed,La prefers to enter into the grain boundaries than Ce and Y prefers to remain in the 2:14:1 phase.Based on these understanding,a series of melt-spun(Ce,La,Y)-Fe-B alloys have been designed.A relatively good combination of magnetic properties with maximum energy product(BH)_(max)=7.4 MGOe,H_(Cj)=400 kA/m,and J_r=0.63 T has been obtained in[(Ce_(0.8)La_(0.2))_(0.7)Y_(0.3)]_(17)Fe_(78)B_6 alloy,together with high Curie temperature(T_c=488 K)and low temperature coefficients of remanence(α=-0.255%/K)and coercivity(β=-0.246%/K). | Xuefeng Liao Jiasheng Zhang Jiayi He Wenbing Fan Hongya Yu Xichun Zhong Zhongwu Liu | 2021 | Journal of Materials Science & Technology2021，，17： | 0 |
| 14 | Grain boundary construction and properties enhancement for hot deformed(Ce,La,Y)-Fe-B magnet by a two-step diffusion process显示文摘The rare earth-iron-boron magnets based on high abundance rare earths(REs)show potential for costeffective permanent magnets but their hard magnetic properties have to be greatly improved.The grain boundary diffusion process(GBDP)is known as an effective way to improve the coercivity of Nd-Fe-B magnets,however,the conventional diffusion method faces a challenge for Ce-based magnets since there is no enough continuous GB layer as the diffusion channel.Here,a two-step(Nd-Cu doping followed by Nd-Cu diffusion)GBDP was introduced for hot deformed(Ce,La,Y)-Fe-B magnet,and the excellent magnetic properties ofμ0Hc=0.63 T,μ0Mr=0.68 T,and(BH)max=72.4 kJ/m^(3)were achieved.The Nd-Cu doping helps the formation of RE-rich GB layer,and then it acts as the diffusion channel for increasing the ef-ficiency of the subsequent Nd-Cu diffusion and results in the increased volume fraction of continuously distributed GB phase,whose paramagnetism was verified by 57Fe Mössbauer spectrometry.Those paramagnetic GB phases help to form the discontinuous domain walls,as observed by Lorentz transmission electron microscopy,and break the magnetic exchange coupling of RE2Fe14B grains.It thus contributes to the coercivity enhancement of the hot deformed magnet with two-step diffusion,which is further proved by micromagnetic simulation.This study proposes a potential technique to prepare anisotropic hot deformed(Ce,La,Y)-Fe-B magnet with high cost-performance. | Xuefeng Liao Weiwei Zeng Lizhong Zhao Qing Zhou Jiayi He Wei Li Xiangyi Liu Hongya Yu Xiaolian Liu Haoyang Jia Jean-Marc Greneche Xuefeng Zhang Zhongwu Liu | 2023 | Journal of Materials Science & Technology2023，，34： | 0 |

| 16 | Microstructure and sliding wear behavior of pseudo-alloy PS45/CuAl8 composite coating sprayed by HVAA technique显示文摘A pseudo-alloy PS45/CuAl8 composite coating was sprayed on steel substrate by high-velocity activated arc spraying (HVAA) process. Its sliding wear behavior at room temperature was evaluated by M-2000 wear tester. For comparison, a single CuAl8 coating was also prepared and tested under the same conditions. It is found that the pseudo-alloy composite coating consists of α-Cu and γ-Ni metallic matrix phases together with homogenously distributed minor Al 2 O 3 , Cr 2 O 3 oxide phases. Moreover, pseudo-alloy coating possesses much better sliding wear resistance than CuAl8 coating due to the enhanced hardness and microstructural homogenization. Fatigue wear and abrasive wear are responsible for the wear-down mechanism of the pseudo-alloy coating. | WU Yaosha a , ZENG Dechang a , LIU Zhongwu a , QIU Wanqi a , YU Hongya a , ZHONG Xichun a , LI Shangzhou a , and MA Yuexin b a School of Materials Science & Engineering, South China University of Technology, Guangzhou 510640, China b Optoelectronic Engineering Department, Zhongshan Torch Polytechnic, Zhongshan 528436, China | 2012 | Rare Metals2012，31，2： | 0 |
| 17 | Effects of Internal Relaxation under Inplane Strain on the Structural,Electronic and Optical Properties of Perovskite BaZrO3显示文摘We present the specific ab-initio calculations that detail the variations of perovskite BaZrO_3 caused by in-plane strain. Specifically, the internal relaxation, which was not captured in the widely used biaxial strain model, was included in a complementary manner to lattice relaxation. Density functional theory as well as a hybrid functional method based on a plane wave basis set was employed to calculate the lattice structure, elastic constants, electronic properties and optical properties of perovskite BaZrO_3. The lattice parameter c exhibited a clear linear dependence on the imposed in-plane strain, but the Poisson's ratio caused by internal relaxation was smaller than the elastic deformation, indicating an 'inelastic' or 'plastic' relaxation manner caused by the introduction of internal relaxation. As a result, the related electronic and optical properties of perovskite BaZrO_3 were also strongly affected by the in-plane strain, which revealed an effective way to adjust the properties of perovskite BaZrO_3 via internal relaxation. | 秦国强 PENG Xiaojun ZHANG Guanglei WU Hongya WANG Caihui YU Gang FU Hua | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，2： | 0 |
| 18 | Geometrically Nonlinear Flutter Analysis Based on CFD/CSD Methods and Wind Tunnel Experimental Verification显示文摘This study presents a high-speed geometrically nonlinear flutter analysis calculation method based on the highprecision computational fluid dynamics/computational structural dynamics methods.In the proposed method,the aerodynamic simulation was conducted based on computational fluid dynamics,and the structural model was established using the nonlinear finite element model and tangential stiffness matrix.First,the equilibrium position was obtained using the nonlinear static aeroelastic iteration.Second,the structural modal under a steady aerodynamic load was extracted.Finally,the generalized displacement time curve was obtained by coupling the unsteady aerodynamics and linearized structure motion equations.Moreover,if the flutter is not at a critical state,the incoming flow dynamic pressure needs to be changed,and the above steps must be repeated until the vibration amplitude are equal.Furthermore,the high-speed geometrically nonlinear flutter of the wing-body assemblymodel with a high-aspect ratio was investigated,and the correctness of the method was verified using high-speed wind tunnel experiments.The results showed that the geometric nonlinearity of the large deformation of the wing caused in-plane bending to become a key factor in flutter characteristics and significantly decreased the dynamic pressure and frequency of the nonlinear flutter compared to those of the linear flutter. | Changrong Zhang Hongtao Guo Li Yu Binbin Lv Hongya Xia | 2023 | Computer Modeling in Engineering & Sciences2023，，8： | 0 |
| 19 | Chemical components in yellow mealworm(Tenebrio molitor L.)reared with tea powder显示文摘The yellow mealworms(Tenebrio molitor L.)were reared by different ratios of tea powder and wheat bran powder mixtures,and weighted every day during the whole 10 days rearing.The content of tea polyphenols,total catechins,catechin(C),epicatechins(EC),epigallocatechins(EGC),epicatechin gallates(ECG),epigallocatechin gallates(EGCG),and nutrition components such as protein and fatty acid in the yellow mealworms were determined after 10 days rearing.The yellow mealworms can put on weight and grow well when the proportion of tea powder belows 80%,while 100%tea powder rearing has no signifi cantly reduced the weight of yellow mealworms.The content of tea polyphenols,total catechins,C,EC,EGC,ECG,and EGCG all enhance signifi cantly along with the increase ratio of the tea powder.The protein content increase more signifi cantly at 50%and 80%ratios treatments than the other treatments.Tea powder added rearing reduces the content of saturated fatty acid,and has a complex effect on the content of unsaturated fatty acid.Comprehensive analysis of the components determined show that 50%ratio is the best for yellow mealworm rearing. | Yanxia Wang Hongya Li Yu Lu Wenyi He Chen Wang Litang Lü | 2022 | Journal of Future Foods2022，2，3： | 0 |
| 20 | Phase precipitation and magnetic properties of melt-spun ternary Gd_(2)Fe_(14)B alloy and advantages of gadolinium substitution in Y_(2)Fe_(14)B alloy显示文摘To take the advantage of gadolinium(Gd) in developing and manufacturing RE-permanent magnets,the magnetic properties and phase precipitation behavior of Gd_(2)Fe_(14)B alloys prepared by melt spinning were investigated in this work.The results show that optimally direct quenched nanocrystalline Gd_(2)Fe_(14)B alloy exhibits the magnetic properties with remanence J_(r) of 0.51 T,coercivity H_(c) of 187 kA/m,and maximum energy product(BH)_(max) of 33.1 kJ/m^(3).It also shows excellent thermal stability with a small negative temperature coefficient of J_(r)(α=-0.066%/K) and a positive temperature coefficient of H_(c)(β=0.171 %/K).The phase precipitations of as spun Gd_(2)Fe_(14)B alloy during melt spinning and over-quenched amorphous Gd_(2)Fe_(14)B alloy during heat treatment were clarified.The magnetic properties of the crystallized alloys annealed at 800℃ are close to those of the optimized directly quenched as-spun alloys,indicating good performance stability under various processes.In addition,the role of Gd substitution in(Y_(1-x)Gd_(x))_(2)Fe_(14)B alloys was systematically studied.Gd substitution can significantly enhance the thermal stability and decrease the irreve rsible remanence loss of Y_(2)Fe_(14)B alloy.With increasing Gd conte nt,Gd-doped Y_(2)Fe_(14)B alloys show continuous enhancement of H_(c) at elevated temperatures.The highest β value of 0.22%/K was obtained in(Y_(0.2)Gd_(0.8))_(2)Fe_(14)B alloy at 300—400 K.Gd substitution is not only effective in improving the exchange coupling effect and corrosion resistance of Y_(2)Fe_(14)B alloy but also superior to Nd in terms of improving the oxidation resistance.The present work has certain instructions for designing and developing new low cost RE permanent magnets with improved thermal and environment stability. | Bang Zhou Yitong Liu Songmao Li Wenbing Fan Xuefeng Liao Jiayi He Hongya Yu Zhongwu Liu | 2023 | Journal of Rare Earths2023，41，7： | 0 |
