摘要: Abstract The stress-induced martensitic transformation of an Fe-30(wt.%)Mn-6(wt.%)Si shape memory alloy has been studied through the tensile deformation and recovery processes. results show that process Fe-Mn-Si alloys can be divided into three stages with different mechanisms. first stage is elastic stage, second one related to γ → ϵ phase transformation, third described as plastic deformation. An appropriate thermomechanical training procedure markedly increase rate close 100%.
