Martensitic transformation in Co_2NiGa ferromagnetic shape memory alloys

摘要

This investigation of the martensitic transformation in ferromagnetic Co_2NiGa shape memory alloys shows that, like in the Ni_2MnGa system, the martensite start temperature is proportional to the valence electron concentration. Al is increasing the transition temperatures when it substitutes Ga and is decreasing them when its substitutes Ni.
