Abstract

The metal particles flow law of the turbine forging process is very hard got to know, due to the complex shape and large deformation of this process. For this situation, a 3D finite element mold was build for this forging process with DEFORM-3D. The results shows that the metal particle flow law in three dimensions is very different in different forging stage and different cross-section of the blade body, the metal particles close to top and bottom die have a smaller displacement than particles in the middle of the cross-section. The particles which close to tenon and shroud have a smaller transverse displacement than particles in the middle blade body. And the particles close to exhaust edge appeared the phenomenon of backflow.
