| 1 | Texture Evolutions in Fe-6.5%Si Produced by Rapid Solidification and Chemical Vapor Deposition显示文摘Fe-Si ribbons and thin sheets with 6.5%Si content were prepared by means of the single roller rapid solidification and chemical vapor deposition (CVD), respectively. The initial textures of rapidly solidified Fe-6.5%Si ribbons were characteristic of the {100} fiber-type, which became weakened during primary recrystallization in various atmospheres.At the stage of secondary recrystallization, the {100} texture formed in Ar and the {110} texture in hydrogen, while there occurred a texture transformation from the {100} type to the {110} type in vacuum with the increase of annealing temperature. For Fe-6.5%Si sheets prepared by Si deposition in cold-rolled Fe-3%Si matrix sheets, their textures were dominated by the η-fiber (<001>//RD) with the maximum density at the {120}<001> orientations.After homogenization annealing, the η-fiber could evolve into the {130}<001> type or become more concentrated on the {120}<001> orientations, depending on the cold rolling modes of Fe-3%Si matrix sheets. | Liang ZUO Guangyong HU Yuhui SHA Claude ESLING | 2002 | Journal of Materials Science & Technology2002，18，6： | 3 |
| 2 | 电场对Al-Mn-Mg合金的微结构和织构形成的影响显示文摘利用透射电子显微镜观察(TEM)和X射线衍射技术(ODFs分析),研究了电场对Al-Mn-Mg合金的回复和再结晶组织演变、再结晶织构的形成和发展的影响。结果表明,电场对再结晶的影响其强度有一个门槛值(3~4 kV/cm),低于此值电场对该合金的再结晶没有明显的影响。强度为4 kV/cm的电场对再结晶形核的影响较大,可抑制Al-Mn-Mg合金的回复和再结晶,促进再结晶立方织构的形成。其主要原因是电场降低了各取向的形变储能,推迟了再结晶进程,抑制储存能小的取向晶核的形成和长大,促进储存能大的S取向晶粒向立方织构择优生长。 | 胡卓超 刘沿东 赵骧 左良 王福 Claude Esling | 2004 | 材料研究学报2004，18，5： | 3 |

| 9 | 具有亚微米晶精细组织Mg-Zn合金薄片的制备(英文)显示文摘具有超细晶结构的金属材料具有优异的力学性能,然而,通过简单的工艺方法制备超细晶结构的块体或者片体金属材料仍然是个难题.镁合金室温变形的各向异性,使制备超细晶结构的镁合金片体材料更是难上加难.目前,某些精密的电子电器领域、大功率镁阳极电池领域以及航空航天领域亟需的镁合金片材大多依靠进口.针对这种现状,本文提供了一个简便的工艺解决方案.首先选取Mg-Zn合金,进行热轧制以及退火.然后,在室温环境下进行快速轧制,通过此工艺成功地制备了具有超细晶组织结构的完好镁合金薄片.本文还对Mg–Zn合金在快速冷轧过程中涉及的材料学问题进行了研究,认为在冷轧过程中多晶面位错滑移的启动是材料获得完好室温冷轧性的关键所在. | 杜兴蒿 洪敏 段国升 武保林 张宇东 Claude Esling | 2015 | Science Bulletin2015，60，5： | 1 |

| 12 | Microstructure and texture analysis of YBCO thick film with peritectic growth on unoriented silver substrate显示文摘YBCO textured thick film was prepared by direct peritectic growth method. Microstructure of the film was characterized. Electron backscattered diffraction(EBSD) technique was applied to the film for quantitative texture analysis. The main difficulty in resolving the orientation of YBCO pseudo-cubic structure was investigated. Automated orientation mapping was performed on YBCO thick film. Local texture was presented in the form of orientation maps. Misorientation distribution and crystal growth characterization in the YBCO thick film were revealed. Large domains with well-aligned YBCO grains were formed. Each domain presented clear in-plane and out-plane textures. | 王珏 MALOUFI Nabila 樊占国 薛向欣 ESLING Claude | 2009 | Journal of Rare Earths2009，27，3： | 1 |
| 13 | Revealing essence of magnetostructural coupling of Ni-Co-Mn-Ti alloys by first-principles calculations and experimental verification显示文摘In this work,the effects of Co doping on the magnetostructural coupling transformation of Ni_(50-x)Co_(x)Mn_(50-y)Ti_(y)(x=0-15,y=12.5-15)Heusler alloys were systematically investigated through the first-princi-ples calculations and experimental verification.The cal-culation result indicates that the doped Co atoms prefer to occupy the Ni sublattice.The Co atoms tend to flock together in terms of the lowest energy principle.Since the formation energy of the austenite is higher than that of the martensite,the alloys will undergo martensitic transfor-mation for the Ni_(50-x)Co_(x)Mn_(37.5)Ti_(12.5)alloys(x=0-12.5).The magnetostructural coupling point of Ni_(50-x)Co_(x)Mn_(37.5)Ti_(12.5)alloys is predicted in the vicinity of x=11-12.Based on the computational composition Ni_(37.5)Co_(12.5)Mn_(37.5)Ti_(12.5),the Ni_(36)Co_(14)Mn_(36)Ti_(14)alloy with magnetostructural coupling near room temperature was experimentally developed by simultaneously increasing the Ti and Co contents.The largest magnetization change(ΔM)and magnetic entropy changes(ΔS_(m))obtained under magnetic field of 5 T for the martensitic transformation in the Ni_(36)Co_(14)Mn_(36)Ti_(14) alloy are about 87.6 A·m^(2)·kg^(-1)and 21 J·kg^(-1)·K^(-1),respectively.The fracture strength and strain for non-textured polycrystalline Ni_(36)Co_(14)Mn_(36)Ti_(14)alloy reach 953 MPa and 12.3%,respectively.The results show that the alloy not only possesses a large magne-tocaloric effect but also has excellent mechanical proper-ties.In addition,the 6 M modulated martensite is evidenced in the Ni-Co-Mn-Ti alloys via transmission electron microscopy technique. | Zi-Qi Guan Jing Bai Yu Zhang Jiang-Long Gu Xin-Jun Jiang Xin-Zeng Liang Run-Kai Huang Yu-Dong Zhang Claude Esling Xiang Zhao Liang Zuo | 2022 | Rare Metals2022，41，6： | 0 |
| 14 | Microstructural Tailoring During Solid-State Transformation by EPM显示文摘Ni-Mn-Ga ferromagnetic shape memory alloys can generate large output with fast dynamic response at the application of the magnetic field and is considered as a new class of functional materials.Since the martensite of these alloys is highly magnetocrystalline anisotropic,introducing a magnetic field during their martensitic transformation could be an effective way to control variant distribution and realize texturation.In this work,some of our recent results achieved in microstructural and crystallographic texture modification by EPM(Electromagnetic Processing of Materials)during solid-state phase transformations of Ni-Mn-Ga alloys were summarized.Moreover,the entropy change induced by magnetic field in Ni-Mn-Ga melt-spun ribbons were also presented. | LI Zongbin ZHAO Xiang Zhang Yudong ESLING Claude ZUO Liang | 2012 | Journal of Iron and Steel Research(International)2012，19，S2： | 0 |
| 15 | Investigation of martensitic transformation behavior in Ni-Mn-In Heusler alloy from a first-principles study显示文摘Composition dependence of martensitic transformations as well as the magnetic properties for the Ni_2 Mn_(1+x)In_(1-x)(0.25≤x≤0.58)alloys were investigated by using the first-principles calculations.Key results demonstrate that the stability of parent austenite(A)decreases gradually with increasing Mn content whilst it is opposite for the martensitic phase.This causes the total energy difference between the austenite and martensite phases increscent with increasing Mn contents.When x=0.33,the martensite transformation during cooling is PA→FA→NM.When x≥0.42,an intermartensitic transformation occurs from modulated 6 M martensite to non-modulated(NM)martensite with the martensite transformation sequence of PA→FA→6 M→NM.The martensitic transformation from austenite to martensite accompanies the transition from ferromagnetic to ferrimagnetic state.This is a typical magneto-structural coupling transformation.The analysis of the density of states demonstrates that the Ni 3 d state plays an important role in the phase stability. | Jinlong Wang Jing Bai Jianglong Gu Haile Yan Yudong Zhang Claude Esling Xiang Zhao Liang Zuo | 2020 | Journal of Materials Science & Technology2020，58，23： | 0 |
| 16 | Composition-Dependent of 6 M Martensite Structure and Magnetism in Cu-Alloyed Ni-Mn-In-Co by First-Principles Calculations显示文摘The composition dependence of the crystal structure and magnetism of the 6 M martensite for the Cu-doped Ni_(43.75)Mn_(37.5)In_(12.5)Co_(6.25) alloy at different site occupations(Cu substitution for Ni, Mn, In, and Co, respectively) is investigated in detail with the first-principles calculations. Results show that the austenite(A) phase exhibits a ferromagnetic(FM) state in all occupation manners, the 6 M martensite possesses an FM state except for the case of Cu substitution at the normal Mn(Mn1) site, and the non-modulated(NM) martensite displays a ferrimagnetic(FIM) state apart from the Cu substitution at the Ni, Mn1, or In sites. The Cu atom destabilizes the A, 6 M, and NM phases regardless of the occupation manner. The one-step martensitic transformation from the A to NM phase occurs in the case of Cu substituting for Mn1, excess Mn(Mn2), or Co;for Cu substituting Ni, a martensitic transformation including 6 M martensite happens, i.e., A → 6 M → NM;however, the martensitic transformation disappears when Cu replaces In site. From the equilibrium lattice constants, it can be speculated that the substitution of Cu for Ni can effectively reduce the thermal hysteresis( ΔT_(Hys)). The magnetic properties are found to be greatly reduced by the substitution of the non-magnetic element Cu for the ferromagnetic Mn atom, whereas the effect is fewer in the remaining cases. It is predicted that the alloy has more favorable properties when Cu replaces Ni. The present results can lay a theoretical foundation for further development of multielement magnetic shape memory alloys. | Xinzeng Liang Jing Bai Jianglong Gu Ziqi Guan Haile Yan Yudong Zhang Claude Esling Xiang Zhao Liang Zuo | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，6： | 0 |
| 17 | Revealing the role of site occupation in phase stability,magnetic and electronic properties of Ni-Mn-In alloys by ab initio approach显示文摘The effects of site occupation on the phase stability,martensitic transformation,and the magnetic and electronic properties of a full series of Ni-Mn-In alloys are theoretically studied by using the ab initio calculations.Results indicate that the excess atoms of the rich component directly take the sublattices of the deficient components of the Ni2Mn_(1+x)In_(1-x),Ni2-xMn_(1+x)In,and Ni_(2+x)Mn_(1-x)In alloys.Nevertheless,the mixed and indirect site occupations may coexist in the Ni_(2+x)Mn In_(1-x)system.The relevant magnetic configurations of the austenite for the four alloy systems have also been determined.The results show that,except for the austenite in the Ni2-xMn_(1+x)In alloys,which tend to be ferrimagnetic,the other alloys all present ferromagnetic austenite.Thus,the site occupation and associated magnetic states are the crucial influencing factors of the phase stability,martensitic transformation,and the total magnetic moment.The electronic structure of the austenite phase also shows that the covalent bonding plays an important role in the phase stability.The key finding of this work is both Ni2Mn_(1+x)In_(1-x)and Ni_(2+x)Mn In_(1-x)alloys serve as the potential shape memory alloys. | Xinzeng Liang Jing Bai Ziqi Guan Jianglong Gu Haile Yan Yudong Zhang Claude Esling Xiang Zhao Liang Zuo | 2021 | Journal of Materials Science & Technology2021，，24： | 0 |
| 18 | Observation of magnetic domain evolution in constrained epitaxial Ni–Mn–Ga thin films on MgO(0 0 1) substrate显示文摘Epitaxial Ni–Mn–Ga thin films have promising application potential in micro-electro-mechanical sensing and actuation systems. To date, large abrupt magnetization changes have been observed in some epitaxial Ni–Mn–Ga thin films, but their origin-either from magnetically induced martensite variant reorientation(MIR) or magnetic domain evolution-has been discussed controversially. In the present work, we investigated the evolutions of the magnetic domain and microstructure of a typical epitaxial Ni–Mn–Ga thin film through wide-field magneto-optical Kerr-microscopy. It is demonstrated that the abrupt magnetization changes in the hysteresis loops should be attributed to the magnetic domain evolution instead of the MIR. | Bo Yang Ivan Soldatov Fenghua Chen Yudong Zhang Zongbin Li Haile Yan Rudolf Schäfer Dunhui Wang Claude Esling Xiang Zhao Liang Zuo | 2022 | Journal of Materials Science & Technology2022，，7： | 0 |
| 19 | First-Principles Investigation on Phase Stability,Elastic and Magnetic Properties of Boron Doping in Ni-Mn-Ti Alloy显示文摘The all-d-metal Ni-Mn-Ti Heusler alloy has giant elastocaloric eff ect and excellent mechanical properties,which is diff erent from the conventional Ni-Mn-based Heusler alloys.In this work,the preferred site occupation,phase stability,martensitic transformation,magnetic properties,and electronic structure of the B-doped Ni_(2)Mn_(1.5)Ti_(0.5)alloys are systematically investigated by the fi rst-principles calculations.The results show that B atoms preferentially occupy the octahedral interstitial.The doped B atoms tend to exist in the(Ni_(2)Mn_(1.5)Ti_(0.5))_(1-x)B_(x)(x=0.03,0.06,0.09)alloy in the form of aggregation distribution,and the martensitic transformation temperature decreases with the increase in the B content.For octahedral interstitial doping,the toughness and plasticity of the(Ni_(2)Mn_(1.5)Ti_(0.5))_(1-x)B_(x) alloys decrease,but the strength and rigidity are greatly enhanced.This is because a small part of the d-d hybridization in ternary Ni-Mn-Ti alloy is replaced by the p-d hybridization in Ni-Mn-Ti-B alloy. | Chenchen Xiong Jing Bai Yansong Li Jianglong Gu Xinzeng Liang Ziqi Guan Yudong Zhang Claude Esling Xiang Zhao Liang Zuo | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，7： | 0 |
| 20 | Impact of B alloying on ductility and phase transition in the Ni–Mn-based magnetic shape memory alloys:Insights from first-principles calculation显示文摘Brittleness is a bottleneck hindering the applications of fruitful functional properties of Ni–Mn-based multiferroic alloys.Recently,experimental studies on B alloying shed new light on this issue.However,the knowledge related to B alloying is limited until now.More importantly,the mechanism of the improved ductility,which is intrinsically related to the chemical bond that is difficult to reveal by routine experiments,is still unclear.In this context,by first-principles calculations,the impact and the correlated mechanism of B alloying were systemically studied by investigating four alloying systems,i.e.,(Ni_(2-x)B_(x))MnGa,Ni_(2)(Mn_(1-x)B_(x))Ga,Ni_(2)Mn(Ga_(1-x)B_(x))and(Ni_(2)MnGa)_(1-x)B_(x).Results show that B prefers the direct occupation manner when it replaces Ni,Mn and Ga.For interstitial doping,B tends to locate at octahedral rather than tetrahedral interstice.Calculations show that the replacement of B for Ga can effectively improve(reduce)the inherent ductility(inherent strength)due to the weaker covalent strength of Ni(Mn)–B compared with Ni(Mn)–Ga.In contrast,B staying at octahedral interstice will lead to the formation of new chemical bonds between Ni(Mn)and B,bringing about a significantly improved strength and a greatly reduced ductility.Upon the substitutions for Ni and Mn,they affect both the inherent ductility and strength insignificantly.For phase transition,the replacement of B for Ga tends to destabilize the austenite,which can be understood in the picture of the band Jahn–Teller effect.Besides,the substitution for Ga would not lead to an obvious reduction of magnetization. | Hai-Le Yan Hao-Xuan Liu Ying Zhao Nan Jia Jing Bai Bo Yang Zongbin Li Yudong Zhang Claude Esling Xiang Zhao Liang Zuo | 2021 | Journal of Materials Science & Technology2021，，15： | 0 |
