During the isothermal constant strain rate compression process, the effect of deformation heating on flow stress increases with increasing equivalent strain rate.
在等温恒应变速率压缩过程中,随着等效应变速率的增大,变形热效应对流动应力的影响程度增大。

The influences of deformation temperature, deformationrate and deformation degree on the flow stress and grain size are different. The deformation degree mainly influences the shape of flow curves.
结果表明:变形温度、变形速率和变形程度对流动应力和再结晶晶粒尺寸均有不同程度的影响。

Present crustal stress values are high, structural deformationrate is fast, intensity of earthquake has an obvious increasing trend, and terrestrial heat flow anomaly is very obvious.
