alloy processed by the heat treatment with no pre-stretch deformation. When the pre-stretch deformation is 3% and 6%, respectively, amounts of tiny T1 and a few of S′ precipitates precipitates are observed in the microstructures of 2A97 alloy. The tensile test results show that the tensile properties of 2A97 alloys are improved via thermo-mechanical treatment. When the pre-stretch deformation......

Abstract: The effect of shape memory of Cu 11.19Al 6.43Mn alloy was measured, an influence of pre deformation degree, recovery temperature and training times on shape recovery of one and two way was studied. Besides, it was analyzed by atom model of crystal deform. Test results show: The alloy has the greatest pre deformation degree of about 4.5%, which can be recovered......
