This figure shows the shape recovery ratio as a function of thermo‐mechanical training cycles when 304 stainless steel are deformed by 1.7% at 77 K. It shows that the thermo‐mechanical training consisting of deformation at 178 K and subsequent annealing at 933 K remarkably enhances the shape memory effect of 304 stainless steel.
