摘要: Abstract The main objective of this study is to implement a reliable FE model the orthogonal machining Nickel based superalloy for prediction microstructural changes occurring during process. A numerical was properly calibrated using an iterative procedure on comparison between simulated and experimental results. user subroutine implemented in code simulate dynamic recrystallization consequently grain refinement hardness variation when cutting performed. Thus, Zener-Hollomon Hall-Petch equations were predict size micro hardness, respectively. In addition, depth affected layer predicted critical strain equation. obtained results proved adequacy proposed showing good agreement
