Article ID: 1003-6326(2005)02-0340-04 Two-way shape memory effect and its stability in Ti-Ni-Hf high temperature shape memory alloy MENG Xiang-long(孟祥龙), WU Ye(吴 冶), CAI Wei(蔡 伟), ZHAO... temperature shape memory alloy(SMA) was systematically studied by bending tests. In the TiNiHf alloy, the martensite deformation is an effective method to get two-way shape memory effect even with a small......
alloy were studied by tensile test and microstructure observation. Using X-ray diffractometry, differential scanning calorimetry (DSC) and semi-quantitative shape memory effect test, the microstructure and shape memory effect were analyzed. It is found that lots of β phase and few α phase are formed in the quenching of Cu-7.5Al-9.7Mn-3.4Zn-0.3Ti-0.14B (mass fraction, %) alloy, a great deal......

INFLUENCE OF PROCESSING ON SHAPE MEMORY EFFECT OF Fe-Mn-Si-Ni-C-RE SHAPE MEMORY ALLOY N.C.Si1,L.B.Qi1,Z.H.Jia1 (1.School of Materials Science and Engineering, Jiangsu University, Zhenjiang 212013, China) Abstract:Effect of carbon, compound RE, quenching temperature, pre-strain and recovery temperature on shape memory effect (SME) of Fe-Mn-Si-Ni-C-RE shape memory alloy was studied by bent......
with a wheel speed of 52 m/s. The uniformity of grain size in heat treated ribbons decreases with increasing wheel speed. Key words: Ti-Ni; melt-spun ribbon; microstructure; shape memory alloy 1 Introduction It has been known that Ti-Ni thin films show shape memory effects comparable to those of bulk materials. The Ti-Ni shape memory alloy (SMA) thin films are expected to be utilized for various......
