Abstract：

Recrystallization and grain growth evolutions during metal forming processes are considered. The finite element user subroutine coupling between the thermo-mechanical and microstructure processes is incorporated to FE code DEFORM-TM. Recrystallization and grain growth evolutions during free upsetting are simulated and the influences of lubrication on grain size are analyzed. The results show that the end forging with fine uniform grain size can be obtained by improving the lubrication.
