Abstract

In this work, the Co 50Fe xV 34- xGa 16 ( x = 1, 2, 3) Heusler alloys were prepared by arc melting. The martensitic transformation near room temperature was excited in the alloys. Owing to the Fe substitution, the alloys are more likely to stabilize in the low-temperature martensitic phase. Thermo-magnetization curves demonstrate that martensitic transformation temperatures increase and martensitic transformation entropy decreases with increasing Fe content. Additionally, the alloy exhibits a shape memory, and the value of strain decreases with increasing Fe content, with a maximum value of ∼ 0.32 % as x = 1.
