摘要：

Ti50Ni50 shape memory alloy cold-rolled and annealed at specific conditions can exhibit a four-stage martensitic transformation. There are two small and two large peaks which are associated with the B2 -> R -> B19' transformations of large grains in the specimen center and that of small grains near the rolling surface, respectively.
