Constitutive Equation of Gatorized Waspaloy in Isothermal Forging Process

详细分析了应变、应变速率、变形温度等变形工艺参数对Gatorized Waspaloy合金低应变速率镦饼中应力-应变曲线的影响。建立了反映该变形过程金属流动规律的本构方程。实现了对该变形过程的数值模拟。

The effect of the deformation pa rameters, such as strain, strain rate, and deformation temperature, on the stres s-strain was analyzed in detail during isothermal forging process.The constitu tive equation, which reflects the metal flow rules during isothermal forging process, was developed.The numerical simulation for the isothermal forging process was realized.
