| 摘 要： | 测试了Ｃｕ－１１．１９Ａｌ－６．４３Ｍｎ合金的形状记忆效应，研究了预变形程度、恢复温度和训练次数对该合金的单向和双向形状记忆效应的影响。结果表明：该合金有一个能完全恢复的最大预变形程度εｍ，它随恢复温度的提高而增大，其最大值约为４．５％；合金的双向记忆效应随训练次数增加而增大。在适当的训练次数和训练温度下，其最大的冷却和加热时的开头恢复量之比值约为３０％。

| 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 completely, and increases with raising recovery temperature; 2) The bi direction memory effect of the alloy is increasing with the raising training times, and at proper training times and temperature its greatest value of the ratio between shape recovery of cooling and heating is about 30%. |
