Abstract: The boundary condition of metal deformation at high temperature using experimental and FEM simulation method, and the effect of friction factor on deformation and stress of ring are studied during for-ming process. Through ring compress experiment and FEM simulation analysis, the regularity of friction can be determined and the range of friction factor in metal hot deformation can also be obtained. Maximum coulomb friction factor is around 0.4.
