Effect of Rare Earth Element Addition on Martensitic Transformation of a Ni-rich Ti-Ni Shape Memory Alloy

摘要：

1at％ Ce, Dy, Gd and Y are added to Ti-50.7at％ Ni alloy individually and the effect of rare earth additions on martensitic transformation of the TiNi alloy are investigated by X-ray diffraction (XRD) and differential scanning calorimetry (DSC). The results show that rare earth additions can increase martensitic transformation temperatures obviously. Especially the effect of Ce addition in Ms is noticeable. Two-step martensitic transformation is observed in Ti-50.2Ni-1Gd and Ti-50.2Ni-1Y alloys, and one-step martensitic transformation is in TiNiRE(RE = Ce, Dy) alloy.
