Abstract

The thermomechanical properties of the shape memory effect and superelasticity due to the martensitic transformation and the R-phase transformation of a TiNi shape memory alloy were investigated experimentally. The transformation line, recovery stress and fatigue property due to both transformations were discussed for cyclic deformation. The thermomechanical properties due to the R-phase transformation were excellent for deformation with high cycles.
