Recovery Strain and Stress Analysis of Fe-Mn-Si Shape Memory Alloy Metal-Lock Staple

Article Preview

Abstract:

A metal-lock staple of Fe-Mn-Si shape memory alloy is firstly used in the repair of large cast iron structure. The paper studied the influence of pre-strain, recovery temperature, thermo-mechanical training on the recovery strain and recovery stress of the metal-lock staple of Fe-17Mn-5Si-2Cr-2Ni-1V shape memory alloy by the tensile testing and recovery stress measurement, and put forward the use principles of the metal-lock staple of the shape memory alloy.
