But too much pre-deformation lead to reducing of strength of the alloy. Therefore the favorable pre-deformation is about 3.5% under the experiment condition.6.
合金在人工时效条件下较适宜的预变形量为3.5％左右，此时合金既具有较好的拉伸强度又兼备较好的塑性。

合金的形状回复率随着预变形量的增加而减小。
The shape recovery decreases with the increasing of predeformation amount.
当预变形量相同时，含0.12%碳的合金的形状记忆效应低于超低碳合金。
The shape memory effect of the alloy with 0.12% carbon was lower than the alloy with ultra-low carbon.
同时，将计算得到的平叉结构变形量作为焊接预变形量应用于实际工艺中，生产出了合格产品。
