Abstract

The effect of rare earth Y on the microstructure, martensitic transformation and mechanical properties of Ni₅₀Mn₂₈Ga_22-xY_x alloys was investigated. The addition of Y results in a change in the microstructure and crystal structure. One-step thermoelastic martensitic transformation is observed in Ni₅₀Mn₂₈Ga_22-xY_x alloys. The martensitic transformation temperature notably increases with the increase in Y content. It is found that the addition of Y significantly improves the compressive ductility of the alloys.
