| 1 | Tailoring the mechanical anisotropy of sintered NdFeB magnets by Pr-Cu grain boundary reconstruction显示文摘Pr_(83)Cu_(17)(wt%) grain boundary reconstruction was applied to prepare sintered NdFeB magnets. The effects of addition amount and annealing on the bending strength were investigated. The results show that Pr_(83)Cu_(17) can not only effectively enhance the bending strength, but also change the mechanical anisotropy in two directions parallel and perpendicular to c-axis. The bending strength perpendicular to c-axis reaches 404 MPa in 10 wt% addition magnet, higher than 348 MPa along parallel direction. This change is attributed to the preferred distribution of boundary phases, i.e., ductile(Nd,Pr)-Fe-Cu phase along perpendicular direction to c-axis and(Nd,Pr)-Fe phase along parallel direction. Moreover, the Cu migration during 480 ℃ annealing is found to be related to this boundary phase distribution. | Minghui Tang Xiaoqian Bao Xuejiao Zhang Xing Mu Kechao Lu Jiheng Li Xuexu Gao | 2019 | Journal of Rare Earths2019,37,4: | 7 |

| 3 | Estimation of tree transpiration and response of tree conductance to meteorological variables in desert-oasis system of Northwest China显示文摘Transpirations of three dominated tree species, namely Mongol Scotch Pine (Pinus sylvestris var. mongolica Litvin), White elm (Ulmus pumila) and Gansu Poplar (Populus gansuensis Wang et Yang) in oasis shelter forest (Linze site) and of two dominated tree species,namely Euphrates Poplar (Populus euphratica Oliv.) and Russia olive (Elaeagnus angustifolia Linn.) in lowland desert (Erjinaqi site) have been estimated using measured sapflow in summer,autumn and winter, 2002 and in spring, 2003. An ENVIS System was used for each site to measure microclimate variables, soil moisture and sapflow every half an hour, and the study time scale is one day. In the 104 days of observation during the growing season at the Linze site, the average daily sapflow of Gansu Poplar is 9.93L·d-1,and the average transpiration per unit leaf area is 1.99mm·d-1.For White elm tree,the daily average sapflow is 4.08L·d-1,while the daily average transpiration per unit leaf area is 0.49mm·d-1.The values for Mongol Scotch Pine are 3.91L·d-1 and 0.25mm·d-1,respectively.In the total 73 days of observation during the growing season at the Erjinaqi site, the daily average sapflows of Russia olive and Euphrates Poplar are 12.1 and 20.97L·d-1,respectively,and the average transpirations per unit leaf area are 0.22 amd 0.31mm·d-1,respectively.In the observation period of the growing season,tree conductances of Mongol Scotch Pine, White elm, Gansu Poplar or Russia olive show an exponential relationship with the daily average air temperature or vapour pressure deficit, but the relationship is not so obvious between tree conductance and global radiation. The transpiration process of each tree species is affected by all the observed four environmental variables. The response of tree conductance to different climatic factors changes with tree species. The effect of the same factor to the same tree species is also variable in different growing stages. The sapflow of every tree species is relatively large in later spring to early summer, and low in summer, and then reaches its largest value in later September. In the mid-November, the sapflow is relatively large, especially the deciduous tree species. This may be characteristic of the tree species in Arid Regions of Northwest China. | CHEN Rensheng KANG Ersi ZHANG Zhihui ZHAO Wenzhi SONG Kechao ZHANG Jishi LAN Yongchao | 2004 | Science China Earth Sciences2004,47,z1: | 5 |
| 4 | Growth of Hydroxyapatite Crystal in the Presence of Origanic Film显示文摘The growth of hydroxyapatite (Hap) crystal in the presence of hexadecylamine was investigated. Due to its high polarity and high charge density, the organic film could increase the ion supersaturation on its surface. Therefore the growth of pure Hap crystals was accelerated. Moreover, the positive headgroups of the organic film could act as recognized nucleation sites and orient the growth of Hap crystals along the<0001>direction. | Yong LIU, Suping HUANG, Xiaohong DAN and Kechao ZHOUState Key Laboratory for Powder Metallurgy, Central South University, Changsha 410083, China | 2004 | Journal of Materials Science & Technology2004,20,2: | 4 |

| 6 | Microstructural evolution and defect formation in a powder metallurgy nickel-based superalloy processed by selective laser melting显示文摘In this study,the selective laser melting(SLM)technology has been employed to manufacture a nickelbased superalloy which was conventionally prepared through powder metallurgy(PM)route.The microstructural features and defects were systematically investigated both prior to and after heat treatment and compared with the PM counterpart.Both solidification cracking and liquation cracking were observed in the SLM specimen in which the grain misorientation and low melting point(γ+γ')eutectic played a vital role in their formation mechanism.Columnar grains oriented along building direction were ubiquitous,corresponding to strong<001>fiber texture.Solidification cell structures and melt pools are pervasive and noγ'precipitates were detected at about 10 nm scale before heat treatment.After supersolvus solution and two-step aging treatments,high volume fractionγ'precipitates emerged and their sizes and morphologies were comparable to those in PM alloy.<001>texture is relieved and columnar grains tend to become more equiaxed due to static recrystallization process and grain boundary migration events.Significant annealing twins formed in SLM alloy and are clarified as a consequence of recrystallization.Our results provide fundamental understandings for the SLM PM nickel-based superalloy both before and after heat treatment and demonstrate the potential to fabricate this group of alloys using SLM technology. | Hongyu Wu Dong Zhang Biaobiao Yang Chao Chen Yunping Li Kechao Zhou Liang Jiang Ruiping Liu | 2020 | Journal of Materials Science & Technology2020,36,1: | 4 |
| 7 | Improving Densification and Mechanical Properties of FeAl/TiC Composites by Addition of Ni显示文摘FeAl/TiC composites were fabricated by hot pressing blended elemental powders. The effects of Ni-doping on thedensification and mechanical properties of the composites were studied. Results show that the density of the com-posites decreases with the content of TiC increasing, and the addition of Ni significantly improves the densificationprocess by enhancing mass transfer in the bonding phase. The mechanical properties of the composites are closelyrelated with their porosity. Besides increasing the density of the composites, the addition of Ni improves the mechan-ical properties by other three effects: solution-strengthening the bonding phase, strengthening the FeAl-TiC interfaceand increasing ductile fracture in FeAl phase. | Yong LIU, Fengxiao LIU, Baiyun HUANG, Kechao ZHOU, Yuehui HE and Zhihong TANGNational Key Lab for P/M, Central South University, Changsha 410083, China | 2003 | Journal of Materials Science & Technology2003,19,1: | 4 |
| 8 | Porous tantalum structure integrated on Ti6Al4V base by Laser Powder Bed Fusion for enhanced bony-ingrowth implants:In vitro and in vivo validation显示文摘Despite the widespread application of Ti6Al4V and tantalum(Ta)in orthopedics,bioinertia and high cost limit their further applicability,respectively,and tremendous efforts have been made on the Ti6Al4V-Ta alloy and Ta coating to address these drawbacks.However,the scaffolds obtained are unsatisfactory.In this study,novel high-interface-strength Ti6Al4V-based porous Ta scaffolds were successfully manufactured using Laser Powder Bed Fusion for the first time,in which porous Ta was directly manufactured on a solid Ti6Al4V substrate.Mechanical testing revealed that the novel scaffolds were biomechanically compatible,and the interfacial bonding strength was as high as 447.5 MPa.In vitro biocompatibility assay,using rat bone marrow mesenchymal stem cells(r-BMSCs),indicated that the novel scaffolds were biocompatible.Alkaline phosphatase and mineralized nodule determination demonstrated that the scaffolds favored the osteogenic differentiation of r-BMSCs.Moreover,scaffolds were implanted into rabbits with femur bone defects,and imaging and histological evaluation identified considerable new bone formation and bone ingrowth,suggesting that the scaffolds were well integrated with the host bone.Overall,these results demonstrated good mechanical compatibility,biocompatibility,and osteointegration performance of the novel Ti6Al4V-based porous Ta scaffold,which possesses great potential for orthopedic clinical applications. | Pengfei Lei Hu Qian Taomei Zhang Ting Lei Yihe Hu Chao Chen Kechao Zhou | 2022 | Bioactive Materials2022,7,1: | 3 |
| 9 | Processing TiAl-Based Alloy by Elemental Powder Metallurgy显示文摘TiAl-based alloys with various compositions (including Ti-48Al, Ti-47Al-2Cr-2Nb, Ti-47Al-2Cr- 2Nb-0.2B and Ti-47Al-3Cr, in mole fraction) had been prepared by elemental powder metallurgy (EPM). The results have shown that the density of the prepared Ti-48Al alloy increases with increasing hot pressing temperature up to 1300℃. The Ti-48Al alloy microstructure mainly consisted of island-like Ti3Al phase and TiAl matrix at hot pressing temperature below 1300℃, however, coarse a2/r lamellar colonies and r grains appeared at 1400℃. It has also indicated that the additions of elemental Cr and B can refine the alloy microstructure. The main microstructural inhomogeneity in EPM TiAl-based alloys was the island-like a2 phase or the aggregate of a2/r lamellar colony, and such island-like structure will be inherited during subsequent heat treatment in (a+r) field. Only after heat treatment in a field would this structure be eliminated. The mechanical properties of EPM TiAl-based alloys with various compositions were tested, and the effect of alloy elements on the mechanical properties was closely related to that of alloy elements on the alloy microstructures. Based on the above results, TiAl-based alloy exhaust valves were fabricated by elemental powder metallurgy and diffusion joining. The automobile engine test had demonstrated that the performance of the manufactured valves was very promising for engine service. | Yong LIU, Baiyun HUANG, Yuehui HE and Kechao ZHOU (National Key Laboratory for Powder Metallurgy, Central South University of Technology, Changsha 410083, China) | 2000 | Journal of Materials Science & Technology2000,16,6: | 3 |
| 10 | Designing high-strength titanium alloy using pseudo-spinodal mechanism through diffusion multiple experiment and CALPHAD calculation显示文摘This study used the pseudo-spinodal mechanism to obtain the ultrafineαphase for designing highstrength titanium alloy.Diffusion multiple experiments were designed to find the composition range of TM-x Mo-y V alloy(TM:Ti-4.5 Al-2 Cr-2.5 Nb-2 Zr-1 Sn)for obtaining ultrafineαphase.CALPHAD results confirm that when the alloy composition is located near the intersection of theαandβphase free energy curves,the alloy will undergo pseudo-spinodal transformation and obtain the ultrafineαphase.The designed TM-6 Mo-3 V alloy has a yield strength of 1411 MPa and an elongation of 6.5%.The strength of the alloy depends on the thickness,fraction of theαphase and the solid solution strengthening effect of the alloying elements.The deformation mechanism of the alloy is the dislocation slip of theαandβphases and the twin deformation of theαphase.The large number ofα/βinterfaces produced by the fineαphase is the main reason for limiting the ductility of the alloy.The use of the pseudo-spinodal mechanism combined with diffusion multiple experiments and CALPHAD is an effective method for designing high-strength titanium alloys. | Di Wu Libin Liu Lijun Zeng Wenguang Zhu Wanlin Wang Xiaoyong Zhang Junfeng Hou Baoliang Liu Jiafeng Lei Kechao Zhou | 2021 | Journal of Materials Science & Technology2021,,15: | 3 |
| 11 | The dynamic responses of lamellar and equiaxed nearβ-Ti alloys subjected to multi-pass cross rolling显示文摘This work gives a comparison on the microstructural characteristics,textural discrepancies,and twinning behaviors of lamellar and equiaxed nearβ-Ti alloys during multi-pass cross rolling with a rolling reduction of 20%,50%and 80%.The results showed that the restoration mechanism of the alloy inβphase is strongly dependent on theαmorphologies,and in comparison,strain path has weaker influences on the grain refinement of theβmatrix.Therefore,the texture intensities of bothαandβphases were weakened owing to the dynamic recrystallization(DRX)of the two phases in the equiaxed microstructure.While,with regard to the lamellar microstructure,dynamic recovery(DRV)of theβphase predominated,forming elongatedβsubgrains.Besides,theαandβmatrix in lamellar microstructures obeyed the Burgers orientation relationship,which was gradually broken down until the final reduction.Lastly,the{1101}twinning exhibits a strong size effect.With the continuous DRX ofαphases,theα-twinning is suppressed owing to progressive grain refinement.The activation ofβ-twinning,namely{332}?113?and{112}?111?,in nearβ-Ti alloys is heavily dependent on the deficientβ-stabilizing elements and the local stress concentration.These findings provide an effective way to obtain ultra-fine grain microstructures of this alloy. | Wei Chen Hande Wang Y.C.Lin Xiaoyong Zhang Chao Chen Yaping Lv Kechao Zhou | 2020 | Journal of Materials Science & Technology2020,36,8: | 3 |
| 12 | A Novel Method for Preparation of TaC Coating on C/C Composite Material显示文摘A new method for preparation of TaC coating on C/C composite material is reported. The amorphous ethylate tantalum jellied as the precursor is prepared and spread densely on the surface of the C/C composite material so as to form a multilayer film. In a graphitization furnace the multilayer film is transformed into TaC coating at various temperatures. Ethylate tantalum film is characterized by FT-IR (Fourier transform infrared) spectra, XRD (X-ray diffraction) and SEM (scanning electron microscopy) and TaC coating is characterized by XRD and SEM. At 1200℃the coating contained TaC and Ta2O5, and at above 1400℃ only TaC is formed. The coating formed at 1600℃ is a continuous stratum structure, and that formed at 1600℃ is a porous net structure. Analysis on thermodynamics and formation mechanism of TaC indicates that, after ethylate tantalum is decomposed, Ta2O5 is first produced and then transformed into Ta2C, and newly formed Ta2C is transformed into TaC by the sufficient C at last. | Hanwei HE, Kechao ZHOU and Xiang XIONG State Key Lab of Powder Metallurgy, Central South University, Changsha 410083, China | 2005 | Journal of Materials Science & Technology2005,21,3: | 3 |
| 13 | Sex-specific responses of tree-ring growth to climate in the dioecious tree Populus cathayana显示文摘Aims Radial growth in response to climate has been reported in many trees,but the sex-specific responses of tree-ring growth associated with altitude in dioecious trees are still poorly known.This study aims to examine whether(i)there are sex-related responses of tree-ring growth to climate in dioecious trees;(ii)these responses could be changed with altitude elevation.Methods The tree-ring width and basal area increment(BAI)were measured over the past 30 years(1982-2011),and the sexual differences in relationship between BAI and time span and correlations between ring width and climatic factors were investigated in Populus cathayana trees at two altitude sites(1,450 m and 1,750 m a.s.l.)in Xiaowutai Mountain,Hebei,north China.Important Findings The BAI was increased over the past 30 years.Trees at high-altitude sites had significantly lower mean ring width and mean BAI than those trees at low-altitude sites(P<0.001).In addition,sexual dif-ferences in tree-ring growth and its response to climate were more pronounced by altitude elevation.Male trees had a significantly larger mean ring width and mean BAI than did females at high-alti-tude sites,whereas no significant sexual differences in these traits were detected at low-altitude sites.Female trees were sensitive to previous October-November temperatures at high altitude but to current February and April precipitation at low altitude(P<0.05),whereas male trees were sensitive to current June temperature at high altitude but to January precipitation at low altitude(P<0.05).Our results indicated that the responses of tree-ring growth to cli-mate are sex dependent and can be changed with altitude elevation. | Kechao Huang Yongmei Liao Tingfa Dong Yanxia Yang Jundong He Huihui Huan Qibing Zhang Xiao Xu | 2018 | Journal of Plant Ecology2018,11,5: | 2 |
| 14 | Recovery of yttrium from deep-sea mud显示文摘Deep-sea mud rich in rare earth yttrium has received lots of attention from the international community as a new resource for Y. A novel process, which mainly includes acid leaching, solvent extraction, and oxalic acid precipitation-roasting, is proposed for recovery of Y from deep-sea mud. A series of experiments were conducted to inspect the impacts of various factors during the process and the optimum conditions were determined. The results show that the Y of deep-sea mud totally exists in apatite minerals which can be decomposed by hydrochloric acid and sulfuric acid solution. The highest leaching efficiency of Y is 94.53% using hydrochloric acid and 84.38% using sulfuric acid under the conditions of H^+concentration 2.0 mol/L, leaching time 60 min, liquid-solid ratio 4:1 and room temperature 25 ℃(only in case of sulfuric acid, when using hydrochloric acid, the leaching temperature should be 60 ℃). Because of the much lower leaching temperature, sulfuric acid leaching is preferred. The counter current extraction and stripping tests were simulated by a cascade centrifugal extraction tank device. Using 10 vol% P204,15 vol% TBP and 75 vol% sulfonated kerosene as extractant, 98.79% Y^(3+) and 42.60% Fe^(3+) are extracted from sulfuric acid leaching liquor(adjusted to pH = 2.0) after seven-stage counter current extraction with O/A ratio of 1:1 at room temperature, while other metals ions such as Al^(3+), Ca^(2+), Mg^(2+)and Mn^(2+) are almost not extracted. The Y^(3+) in loaded organic can be selectively stripped using 50 g/L sulfuric acid solution and the stripping efficiency reaches 99.86% after seven-stage counter current stripping with O/A ratio of 10:1 at room temperature, while only 2.26% co-extracted Fe^(3+) is stripped. The Y^(3+) of loaded strip liquor can be precipitated by oxalic acid to further separate Y^(3+) and Fe^(3+). The precipitation efficiency of Y^(3+) in loaded strip liquor can be 98.56% while Fe^(3+) is not precipitated under the conditions of oxalic acid solution concentration 200 g/L, quality ratio of oxalic acid to Y of 2, and precipitation time 0.5 h. And the precipitate was roasted at 850 ℃ for 3 h to obtain the oxide of Y in which the purity of Y_2 O_3/REO is 79.02% and the contents of major non-rare earth impurities are less than 0.21%.Over the whole process included acid leaching, solvent extraction, and oxalic acid precipitation-roasting,the yttrium yield is 82.04%. | Kuifang Zhang Zhiqiang Liu Changyong Sun Hongyang Cao Kechao Zhu Wei Zhu Wei Li | 2018 | Journal of Rare Earths2018,36,8: | 2 |
| 15 | Ni/ZrO_2 Catalysts Synthesized via Urea Combustion Method for CO_2 Methanation显示文摘A series of Ni/ZrO_2 catalysts were synthesized by urea combustion method for CO_2 methanation.The effects of zirconium precursors and urea dosage on the structure and catalytic performance of the catalysts were tested.Results showed that the Ni/ZrO_2–O catalyst derived from zirconium oxynitrate hydrate exhibited better catalytic activity than the Ni/ZrO_2 catalyst because of its higher Ni dispersion and smaller Ni particle size.In addition,the urea dosage significantly influenced the low-temperature activity of the catalysts by affecting the metal–support interaction,Ni dispersion,and Ni particle size.The Ni/ZrO_2–O-0.4 catalyst with a urea-to-nitrate molar ratio of 0.4 exhibited the best catalytic activity owing to its moderate metal–support interaction,highest Ni dispersion,and smallest Ni particle size,achieving 69.2% CO_2 conversion and 100% CH_4 selectivity at 300℃,0.1 MPa,and a weight hour space velocity(WHSV)of 50,000 mL/(g·h).Moreover,the urea combustion method can lead to the entire phase transformation from monoclinic ZrO_2 to tetragonal ZrO_2 accompanied by the incorporation of oxygen vacancies in the ZrO_2 lattice.This phenomenon can also be related to the high catalytic activity of the as-prepared catalysts. | Zhenhua Li Lijuan Zhang Kechao Zhao Li Bian | 2018 | Transactions of Tianjin University2018,24,5: | 2 |
| 16 | Microstructures, mechanical properties, and grease-lubricated sliding wear behavior of Cu–15Ni–8Sn–0.8Nb alloy with high strength and toughness显示文摘Alloys used as bearings in aircraft landing gear are required to reduce friction and wear as well as improve the load‐carrying capability due to the increased aircraft weights.Cu–15Ni–8Sn–0.8Nb alloy is well known for possessing good mechanical and wear properties that satisfy such requirements.In this study,the microstructure,mechanical properties,and grease‐lubricated sliding wear behavior of Cu–15Ni–8Sn–0.8Nb alloy with 0.8 wt%Nb are investigated.The nanoscale NbNi3 and NbNi2Sn compounds can strengthen the alloy through the Orowan strengthening mechanism.A Stribeck‐like curve is plotted to illustrate the relationship among friction coefficient,normal load,and sliding velocity and to analyze the grease‐lubricated mechanism.The wear rate increases with normal load and decreases with sliding velocity,except at 2.58 m/s.A wear mechanism map has been developed to exhibit the dominant wear mechanisms under various friction conditions.When the normal load is 700 N and the sliding velocity is 2.58 m/s,a chemical reaction between the lubricating grease and friction pairs occurs,resulting in the failure of lubricating grease and an increase in wear. | Jinjuan CHENG Mincong MAO Xueping GAN Qian LEI Zhou LI Kechao ZHOU | 2021 | Friction2021,9,5: | 1 |
