Coupled Thermo-Mechanical-Metallurgical Analysis of an Hot Forging Process of Titanium Alloy

In the present paper a numerical FEM model for the analysis of a forming process of a complex shape component is presented. The model, developed using the commercial implicit code DEFORM™, can take into account both the thermo-mechanical evolution and the microstructural evolution of the considered material. In this case the Ti-6Al-4V titanium alloy was because it was possible to carry out a very good characterization into a FEM ambient. In particular the code can calculate the phase distribution of the main phases of the alloy as consequence of the thermo-mechanical history of the material during a hot forging process. At the end of the simulation the output data was showing to analyze the validity and the quality of the model by a numerical point of view.

Hot Forging Process

The rigid-visco-plastic finite element model for the hot forging process of transmission shaft flange yoke was established, and two forging schemes of different male die shapes were simulated. As for the present forming process, the forming defects were indentified and analyzed. Based on the simulating results the decision-making process was obtained, and a preforming die and a final forming die with proper structures and longer life were designed. The transmission shaft flange yoke part produced by this process is excellent in dimension tolerance and mechanical property. This process is profitable reference for producing the similar type of forks with complex shape.
