近期,一些文献陆续报道了无镍β钛合金的形状记忆效应和超弹性行为的研究结果,这些合金系如Ti-Mo-Al,Ti-Nb-Sn,Ti-Mo-Ga,Ti-Nb-Al,Ti-Nb及Ti-Nb-Zr-Sn。人们希望用其替代TiNi形状记忆合金,以消除TiNi合金作植入件对人体产生的过敏或致癌影响。
Recently, some reports have reported the shape memory effect and the super-elastic behavior of nickel-free beta titanium alloys such as Ti-Mo-Al, Ti-Nb-Sn, Ti-Mo-Ga and Ti-Nb- Al, Ti-Nb and Ti-Nb-Zr-Sn. It is hoped that TiNi shape memory alloy can be used instead of the TiNi alloy as an implant to cause allergic or carcinogenic effects on the human body.
