Martensitic transformation and shape memory effect of nicomnsn high temperature shape memory alloy

This article studies the dependence of martensitic transformation on Mn:Sn ratio in Ni43Co7Mn502xSnx alloy and the shape memory behavior of Ni 43Co7Mn43Sn7 in detail. The results show that all the transformation temperatures show a linear decrease with the decrease of Mn:Sn ratio. The similar tendency is also found in the change of Tc. Ni43Co7Mn43Sn7 alloy exhibits a moderate shape memory effect and the maximum shape recovery strain is 2.96%. Temperature memory effect is also observed in Ni43Co7Mn43Sn7 alloy. ?
