文摘A mathematic model for dynamic and static recrystallization of Mn18Cr18N steel is presented.Hot expanding extrusion forming and air cooling process of 600 MW retaining ring has been simulated by the combination of thermos coupled rigid viscoplasitic FEM with this model,and grain size distribution on cross section of ring is shown.The essential results can be provided for use of the new technique.
