The stress-strain-temperature relationship associated with the R-phase transformation in TiNi shape memory alloy was investigated experimentally and theoretically. The main results were summarized as follows. ( 1 ) The R-phase transformation showing a clear yielding stage on the stress summarized as follows. ( 1 ) The R-phase transformation showing a clear yielding stage on the stress-strain-temperature relationship appeared in a certain range of shape memory processing tempera-temperature plane almost overlapped each other. Both transformation regions were small for high shape memory processing temperature. ( 3 ) The constitutive equation considering the volume fraction of the R-phase described well the deformation behavior, such as the shape memory effect, pseudoelasticity and partial pseudoelasticity.
