Abstract：Progress in the studies on the thermo-mechanically coupled cyclic deformation of NiTi shape memory alloys (SMAs) is reviewed and commented. At first, the uniaxial and multiaxial cyclic deformation of NiTi SMAs and its strong thermo-mechanically coupled effect are summarized, and the physical mechanism of functional degeneration during the cyclic deformation is outlined; then, three types of cyclic constitutive models constructed in the macroscopic and microscopic senses, are addressed, and the capabilities of representative models to describe the thermo-mechanical cyclic deformation of NiTi SMAs are verified; finally, some suggestions are presented for the future work by summarizing the shortcomings of existing researches. In the content about the constitutive model, the crystal plasticity based thermo-mechanical coupling ones proposed by the authors and their co-workers are mainly introduced, and the effects of multiple inelastic mechanisms and strongly nonlinear thermo-mechanical coupling on the cyclic deformation of NiTi SMAs.
