摘要
用热加工模拟试验机对X65钢进行了高温压缩试验，建立了试验用钢的奥氏体热变形方程式及动态再结晶临界条件回归方程式。根据动态再结晶动力学。
The high temperature compression tests of X65 steel have been carried out by using THERMECMASTOR-Z simulator. The hot deformation equation of austenite and the critical regression equations of dynamic recrystallization have been established. On the basis of recrystallization dynamics, the dynamic recrystallization rate equation has been established by means of σ-εcurves as followsXd=1-exp[-2.58(ε/εp-0.83)1.52] εp=1.25×(1Nz-26.97)/17.14 Z= ·exp(364.5/RT)
