Research on Compression Properties of Ni-Ti Shape Memory Alloys

Abstract:

Quasi-static and dynamic compressive mechanical properties of Ni-Ti shape memory alloys have been investigated by using electronic universal testing machine and Split-Hopkinson Pressure Bar (SHPB), respectively. The experimental results show that the dynamic yield stress and the fracture stress are higher than those in the static. Martensitic phase transformation is induced by stress before the plastic deformation. The critical stress of SIM and the slope of stress plateau increase with the increase of strain rates.
