Abstract
The precipitation strengthening effect of Ti50Ni15Pd25Cu10 shape memory alloy is effectively promoted by adding a small amount of vanadium. Cu-rich TiPdCu precipitates formed when Ti50-xNi15Pd25Cu10Vx alloys were aged at 573 K for 1 h. The shape memory effect, the pseudoelasticity, and the elastocaloric effect were effectively improved after precipitation strengthening. ? 2021 Elsevier B.V.
