Abstract

The effect of isothermal ageing on the microstructure, martensitic transformation and mechanical properties of Ni₅₃Mn_23.5Ga_18.5Ti₅ alloy has been investigated. The results show that Ni₃Ti precipitates are observed in aged samples. The martensitic transformation temperature decreases remarkably with increased ageing time, while the martensitic structure of these alloys is five-layered martensite at room temperature. Additionally, Ti doping can significantly enhance the compressive strength and improve the ductility of Ni-Mn-Ga alloy with the appropriate ageing treatment.
