Abstract
A shape memory alloy consisting, by atomic ratio, of V 0.25-2.0% and the balance of Ni and Ti, an atomic ratio of Ni and Ti being 0.96-1.06. The shape memory alloy has a good workability and a reduced temperature difference between a martensitic transition start point and an austenitic transition finish point. When the atomic ration of Ni/Ti is 0.96-1.02, the martensitic transition start point is the room temperature or higher. When the atomic ratio of Ni/Ti is 1.02-1.06, the martensitic transition start point is the room temperature or lower. The shape memory alloy has a pseudo elasticity.
