摘　　要：用恒载荷法研究了铸态Zn 5Al合金相变超塑性的变形特征。结果表明 ,铸态Zn 5Al合金相变超塑性变形符合线性法则和低应力特征 ;其铸态下的伸长率随着载荷的减少、循环频率的升高和保温时间的延长而增加。The transformation-induced super plastic deformation of Zn-5Al cast alloy was investigated by the constant load method.The test results show that the transformation-induced super plastic deformation of the Zn-5Al cast alloy accorded with the law of linear relationship and the character of the low stress;the elongation of this alloy increased with decreasing the load,increaded with enhancing the cycle frequency,or with prolonging the holding time.
