Abstract

The effect of rare earth element neodymium (Nd) addition on the microstructure and phase transformation behavior of Ni50Ti47Fe2Nd1 shape memory alloy was investigated by scanning electronic microscope, X-ray diffraction and differential scanning calorimetry. The results show that the microstructure of Ni-Ti-Fe-Nd quaternary alloy consists of NiNd3 phase, NiTi2 and the NiTi matrix. A one-step martensitic transformation is observed in the alloys. The martensitic transformation start temperature Ms 54.110C.
