Abstract Scope Superelastic nitinol finds a wide range of applications in the aerospace and medical industries due to its shape-recovery ability. In most of its applications, nitinol is subjected to cyclic loads within its superelastic stress-strain range. Due to the complex nature of the martensitic transformations, the existing fatigue theories do not accurately predict the nucleation and propagation of fatigue cracks in superelastic nitinol, which may endure fatigue damage that leads to structural and/or functional degradation. It has been shown that, other than the surfaces, the major fatigue crack initiation sites are the microstructural imperfections such as voids and non-metallic inclusions. Among all the factors affecting fatigue performance, the size effect has received less attention. In this research, superelastic nitinol wires with three different diameters are examined to explore the effect of wire size on the nucleation and propagation of fatigue cracks near the wire surface and around the non-metallic inclusions.
