? 2021 Elsevier B.V.Shape Memory Alloys (SMAs) have shown superior mechanical properties including improved wear resistance compared to their conventional counterparts of the same surface hardness. Available wear models cannot estimate a wear coefficient for SMAs, since they do not consider the effects of phase transformation and the related phenomena. This study presents a methodology considering thermomechanical behavior of shape memory alloys in sliding wear. Wear analysis is carried out for a superelastic SMA under different loads and temperatures, and the results are validated by experimental findings. The proposed approach introduces a constant wear coefficient at different loads and temperatures supporting its reliability for quantitative description of wear in an SMA.
