Abstract: The temperature of hot-forming and solution is determined for FeMnSiCrNiCo anti-corrosion alloy. The influence of pre-deformation, annealing temperature and training on shape memory effect is investigated with the analysis of microstructures. The results show that η_m descends and ε_m reaches a optimum point along with pre-deformation increasing, the shape memory effect(SME) and microstructure of FeMnSiCrNiCo alloy vary with training annealing temperature changing. Annealing temperature plays an important role in training effect and parent matrix sub-structure is an essential factor for the SME of FeMnSiCrNiCo alloy.
