Abstract:

This paper presents the results of physical and numerical simulation of forging followed by controlled-cooling processes. Rheological, microstructural and phase transition models for the simulation were developed using Gleeble 3800 and DIL 805A/D. All models were implemented into the FE code. The microstructure and mechanical properties of final products were predicted. Results of simulation were compared with mechanical properties of actual forging.
