| Abstract: | NiTi shape memory alloys have attracted great attention in engineering and medical fields in recent year due to their excellent shape memory effect and biological compatibility. The research on the micromechanism of shape memory effect in NiTi alloys is making progress step by step. This paper presents the main properties of NiTi alloys and the main factors which influence the shape memory effect of the alloy, summarizes present studies on the micromechanism of shape memory effect and superelasticity in NiTi alloys, finally points out some questions about the alloys to be studied. |
