Abstract

The effect of thermal cycling on the microstructure, martensitic transformation behavior and shape memory characteristic of the dual-phase Ni₅₈Mn₂₅Ga₁₇ high-temperature shape memory alloy was investigated. The Ni₅₈Mn₂₅Ga₁₇ alloy showed high thermal stability upon cycling up to 500 thermal cycles between 298 and 923 K without obvious differences in its microstructure and martensitic transformation behavior. Shape memory strain decreased slightly after 500 thermal cycles but remained over 2.6%.
