In this paper, finite-element based approach to optimized preform design is applied to reduce forming load in fabricating a difficult-to-forge product of pancake shape. A successful hot forging process with optimized preform or blocker is developed for a pancake-type forging with many holes. The process is characterized by the internal pockets or cavities between material and die which can reduce the magnitude of hydrostatic pressure at the final stroke. Since the hydrostatic pressure and/or forming load increases drastically after the material fills the internal cavities and the increased forming load or hydrostatic pressure may lead to die fracture, sound metal flows are very important for success of the process design especially for pancake-type forgings with complicated faces. A thermoviscoplastic finite element method is employed to predict the plastic deformation during the process with high accuracy.
