Thermal-induced martensitic transformation of NiTi shape memory alloy promoted by pulse current

The effect of transient and high-energy pulse current (THEPC) on the phase transformation behavior of the Ti -50.8 at.% Ni shape memory alloy was investigated in this study. The results show that the THEPC increases the start temperature of martensitic transformation, which indicates the facilitation of the thermal-induced martensitic transformation. Meanwhile, the transient and high-energy effect of the pulse current changes the phase transformation sequence of NiTi alloy during cooling, making it from one-stage phase transformation of A-*M to two-stage of A-*M1 and A-*M2.

Automated summary

This study investigates the effect of transient and high-energy pulse current on the phase transformation behavior of NiTi shape memory alloy. The results show that THEPC increases the start temperature of martensitic transformation and changes the transformation sequence.
