Superelasticity of Geometrically Graded NiTi Shape Memory Alloys
Metals, 2023 A stress plateau with a strain of 5–8% normally occurs during the stress-induced martensite transformation (SIM) of NiTi shape memory alloys. Within the stress plateau, the correlation between the stress and strain is lost, which limits their application
