  • Thermal-mechanical coupled numerical simulation of GH4169 alloy during cross wedge rolling(CWR) was carried out using the finite element software DEFORM-3D.The metal flowing and temperature distribution of rolled pieces,and the rolling force and torque between the rolled piece and the roller were obtained and comparatively analyzed with 45# steel.The results show that the axial metal flowing of GH4169 during CWR is different from that of 45# steel,and the axial metal flowing at the surface substantially lags behind that at the center.All the energetic parameters are much greater than 45# steel's,and the maximum value is 2.15 times that of 45# steel.Meantime the deformation temperature is always higher than 45# steel's,and the maximum temperature rise is 6.21% more than that of 45# steel.
