Description

An effect of aging on shape memory behavior was investigated for Mn - 15 at % Cu alloy. It was revealed that aging of the alloy at 693 K significantly improves both shape memory effect (SME) and reversible shape memory effect (RSME). The reason of improved SME can be attributed to the decrease in the axial ratio, c/a, of fct martensite phase at room temperature. The enhancement of RSME might be related to the formation of Mn-rich zones associated with a higher antiferromagnetic ordering temperature. (orig.)
