Abstract: The blade precision forging is one of the advanced techniques in modern metalworking process.It is very important to investigate the metal deformation behaviors in detail.According to the production data, the forming process of the blade cross-section is simulated by rigid-viscoplastic finite element me-thod（RVPFEA）.The material flow and effective strain distribution are obtained under different friction and tool velocity conditions for the rate sensitive mateials Pb and Ti-6AI-4V, respectively.The effects of friction and flash land on material flow are discussed.The structure are compared with effective strain for different locations in forging.The results show that the simulations by rigid-viscoplastic finite element method can describe distinctly the whole process of blade forging and provide a great deal of information for forging preform design and prediction of defect formation and location.The meshes drawn by computer are in good agreement with the results of experiments. For the complicated boundary conditions in blade forging, some methods are given to treat arbitrarily shaped dies and complex fractional conditions in implement of FEM.The calculation shows that the program can be widely used to analyse the metalforming processes.
