Abstract

A loss function (LF) based on the distribution of thermalmechanical parameters was proposed referring to the concept of Taguchi method to explore the method of evaluating microstructure homogeneity in disk forging. The forging process of the TC11 titanium alloy blisk and the subsequent evaluation of microstructure homogeneity were analyzed by using FEM and the proposed method. The experiment was performed. The comparison results show that, for TC11 titanium alloy blisk forging, the LF in case 2 proposed in this paper can more appropriately evaluate the microstructure homogeneity, and that the blisk forging with satisfied technical requirements can be obtained when the LF values are in the range of 0.33~0.44.
