Computer Simulation of Microstructure Evolution during Hot Forging of Waspaloy

미세조직 변화를 고려한 열간 단조 공정에서의 유한요소해석

Computer simulation of microstructure evolution during hot forging process is of great interest in recent years. Recrystallization model and grain growth model which use a phenomenological approach were summarized. For the waspaloy, upsetting process and cogging process were simulated using $DEFORM^{TM}$ and the change in grain size were investigated in each deformation procedure.
