Constitutive Relationship of TC11 Alloy and Its Application in Hot Die Forging Process of Disc Component Using Finite Element Method

Zhu Lei1, Zhang Maicang1, Dong Jianxin1, Pang Kechang2 (1. School of Material Science and Engineering, University of Science and Technology Beijing, Beijing 10083, China) (2. Special Steel Processing Center of Bao Steel(Group), Shanghai 200940, China)  
Based on test data from hot process simulator, a Kumar type constitutive equation for TC11 alloy is established in this paper. Applying this constitutive equation in commercial FEM software of MSC /Autoforge, hot die forging process of TC11 alloy turbine disc is then simulated. The results show that the Kumar-type constitutive relationship meets the practical need to a great extent.
