The ideas currently being developed regarding the physical nature of the reversible martensitic transformations seem to suggest heterogeneous development of microstrains in a crystal and activation, independent of space and time, of mechanisms of phase-twin or dislocation plasticity, in the processes of both deformation and recovery. On the basis of these propositions it is possible to simulate the shape recovery of alloys by simply superimposing the kinetics of shape recovery after individual stages of prior deformation. This paper reports the results of experiments simulating the reverse shape-memory effect in TiNiFe. Authors conclude that it is possible to simulate the shape recovery of materials with shape memory by superposition of the kinetics of recovery initiated by the corresponding stages of prior deformation.
