工艺参数对Rene'95粉末高温合金盘件等温锻造过程影响的模拟分析

Application of FEM Simulation to the Effects of Working Parameterson Isothermal Forging of AsHIPed Rene′95 Alloy

采用大变形刚粘塑性有限元法模拟Ｒｅｎｅ′９５粉末高温合金盘件等温锻造过程，分析了压机速度、摩擦对变形的影响。

n the present paper,the process of isothermal forging of asHIPed Rene′95 is simulated by using large deformation rigidviscoplastic finite element method(FEM).The effects of the velocity of the press and the friction on the deformation are analyzed.
