Finite Element Simulations of Microstructure Change in Cutting Process of Inconel 718

  • 摘要: 为对718镍合金切削过程加工表面晶粒细化和微硬度变化较为准确的仿真预测,首先将仿真与实验对比,选取一组最佳的本构模型参数,其次通过有限元校准法对仿真过程的相应物理参数进行优化,使得仿真的相关参数达到最优,并通过对Deform-2D进行二次开发,运用Zener-Hollomon方程对718镍合金正交切削过程中动态再结晶过程仿真,运用Hall-Petch方程对加工表面和次表面微硬度变化仿真,最终得到了718镍合金正交切削过程加工表面晶粒尺寸和微硬度的变化,为718镍合金表面加工质量的评估提供了较为可靠的依据。
