本文确定了超塑变形多重机制效应的存在,并根据这个效应,分析了超塑变形的主要参数,m,P和Q_a的变化规律及产生这些变化的原因.
In this paper, the existence of multi-mechanism effect of superplastic deformation was confirmed. Based on this effect, the main parameters of superplastic deformation were analyzed. The variation rules of m, P and Q_a and the reasons for these changes were analyzed.
