合金在高应变速率的变形中通过动态再结晶可获得更细的晶粒尺寸，其断裂时总延伸率在135%左右。
They also show that a finer grain size can be obtained by dynamic recrystallization during superplastic deformation at a high strain rate, but the total elongation to failure is limited in about 135%.
利用引伸计拉力试验中的规定总延伸强度可以评价灰铸铁的拉压疲劳极限，也可以利用该数值作为预计的疲劳极限，用于拉压疲劳试验应力水平的选取。
The proof strength can be used to evaluate the tension-compression fatigue strength of gray cast iron, and also used as the stress level of the tension-compression fatigue test.
