Abstract

Inhomogeneous deformation can result in great difference in microstructures and mechanical properties of forgings, especially for those of difficult-to-deform materials. The method of billet shape optimization based on sensitivity analysis for improving the deformation uniformity within forgings during hot working processes was presented in this paper. As an example, the preform optimization for a typical IN718 turbine disk forging was performed. The results of the optimal billet were presented and compared with those of the cylinder one. The results show that the deformation homogeneity within the turbine disk forging can be improved significantly by using of the optimal billet.
