摘要：

Transformation sequence of Ti50Ni50 shape memory alloy after 35% cold-rolling and subsequent recrystallization annealing have been investigated. Four transformation sequences of Stages I-IV on different annealing conditions are proposed. Stage I corresponds to an incomplete transformation, whereas Stage II represents the four-step MST with two large and two small peaks associated with B2 -> R -> B19' transformation of large grains in the specimen center and that of small grains near the rolling surface, respectively. Stages III and IV are the complete B2 <-> R <-> B19' and B2 <-> B19' transformation sequences, respectively. (c) 2006 Elsevier B.V. All rights reserved.
