Through the finite element numerical simulation, the research method of selecting GH4169 alloy blade final forging's typical section and tracking the feature points on the pre-forging in the whole forging process of forming metal flow characteristics and its changing trend was used. Thus its final forging evolution rule under different process parameters was comprehensive revealed. The results show that the distribution of equivalent strain and stress field along with the increase of beginning forging temperature become more uniform; the upper die-pressing speed is of strong sensitivity for equivalent stress field, temperature field and load-stroke curves, the larger deformation rate can lead to large temperature increase, also easy to make the internal organization of the grain lattice being deformed to produce large additional stress and stress concentration, and the earlier the instantaneous peak load appears, the more the times are; the increase of friction factor have a greater impact on the lowest body temperature increasing of the blade central longitudinal section, which could increase the forging difficulty and make uneven deformation.
