摘　　要：综合应用热模拟试验、非线性回归方法和Monte Carlo法,提出了一个构建和优化完整的连续动态再结晶材料本构关系模型的新方法.通过一个完整的09CuPTiRE钢板热变形本构关系模型的建立和优化,验证了该方法的有效性.By integrating the thermal simulation test, nonlinear regression and Monte Carlo methods, a new method was proposed to construct and optimize the constructive relationship model of the material, which is of completely and continuously dynamic recrystallization. In addition, the effectivity of this new method was validated based on the construction and optimization of the constructive relationship model of 09CuPTiRE steel hot deformation.
