摘要：

A three-dimensional finite element analysis of the breakdown of cast alloy 718 ingot by cogging using an industrial process schedule was conducted, Six cogging passes were simulated for non-isothermal conditions and the predicted loads were compared to the loads recorded during industrial cogging practice. Microstructural models were implemented to predict the resulting microstructures as a function of local temperature, strain, and strain rate. These predicted microstructure values, which included percent recrystallization and recrystallized grain size, were compared with the industrial data.
