摘要：
The modification of Fe-14Mn-5Si-9Cr-5Ni shape memory alloys (SMAs) by copper addition was carried out, aiming at further enhancing its corrosion resistance. The results of electrochemical potentiodynamic measurement and immersion test show that copper can remarkably improve the corrosion resistance in Cl- solution. Otherwise, it is found that copper cannot markedly affect the mechanical properties nor the shape memory effect (SME). As for the effects of copper on Fc-Mn-Si based alloys, the austenite strengthening is one of the key factors to improve SME.
