Strain-induced martensitic transformation in biomedical Co-Cr-W-Ni alloysZi-Yi Zhu1,Li Meng2,Leng Chen11. School of Materials Science and Engineering,University of Science and Technology Beijing2...-induced martensitic transformation(SIMT) process in biomedical Co-Cr-W-Ni alloys were investigated.The experimental results show that theε-hexagonal-close-packed phase was preferentially formed at the Σ3......
Ni-Mn-Ga alloys were investigated. The experimental results show that the Sm doped alloys also undergo a thermal-elastic martensitic transformation and reverse transformation during cooling and heating process and the addition of Sm decreases the martensitic transformation temperature and Curie temperature in different degree respectively. Ni-Mn-Ga alloys of adding Sm still possess Heusler......
studied. When the composition of Ni in these alloys was constant, increasing Mn and reducing Ga contents make martensitic transformation temperatures rise obviously. Simultaneously, thermal hysteresis... ferromagnetism and properties of thermoelastic martensite phase transformation.

of the as-deposited films were determined by X-ray diffraction and substrate-curvature method.The phenomenon of stress-suppressed martensitic transformation was observed. It isconsidered that the residual... during the martensitictransformation. Key words:martensitic transformation; residual stress; TiNi; thin film; shape memory alloy; [全文内容正在添加中] ......
TEM Studies on Martensitic Transformation in Fe-Cr-W-V-C Alloy伍尚华,刘禹门摘 要:<正> The martensitic transformation inFe-Cr-W-V-C alloy has been investigated byTEM.The habit plane of martensite is near (252)f,the austenite/martensite orientation relationship isKurdjumov-Sachs’.In the martensite plates thereare twins on (112)[ 1]b,dislocation tangles......
Irreversibility and transformation randomness of thermoelastic martensitic transformation in Ni–Ti alloysTian-Wei Liu,Yan-Jun Zheng,Li-Shan CuiDepartment of Materials Science and Engineering, China... defects and more obvious irreversibility.On the other hand,defects generated in thermoelastic martensitic transformation are responsible for the hysteresis of transformations.Therefore,the randomness......

Chinese Conference on Martensitic Transformation(CCOMAT)张修睦摘 要:<正> The 1990 Chinese Conference onMartensitic Transformation (CCOMAT)has been successfully held in Qinhuangdao,a beautiful seaside city in China,on August18-22,1990.The conference was organizedby Hebei Institute of Technology and HebeiBranch of the Chinese Society of Metals.关键词:......
elements and the matrix. A large recovery strain of the SMA elements (e.g., up to 8% for TiNi) can be involved during the thermal martensitic transformation, which makes the composite more susceptible... study of the reverse martensitic transformation in prestrained TiNi shape memory alloy in different composites[J].
