Abstract：

3D simulation for the forging of TC6 alloy airfoil blade was carried out with the help of the elastic-plasticity finite-element method. According to the simulation, the effects of processing parameters on the temperature, equivalent stress and equivalent strain were studied in the forging process，and the distribution of residual stress after unload was also discussed. The results indicate that the deformation temperature, friction factor and strain rate have significant effects on the temperature and equivalent stress, but have no significant effects on the equivalent strain. The distribution of the residual stress after unload is inhomogeneous during final forging, the residual stress on the edge of the blade is higher than that inside the blade and the residual stress concentration zones after unload appear in the stress concentration zones during the forging process.
