Computer Simulation on Formation of Precision Forgings of Titanium Alloy and Superalloy

The deformation features are analyzed for titanium alloy and superalloy during isothermal/hot die forging process, and proper finite element models with appropriate parameter values are determined. On the platform of DEFORM software, the formation processes of vane-integrated disk and compressor disk, made of titanium alloy and superalloy respectively, are simulated and analyzed. Based on the simulation results, some important suggestions to the process design and parameter determination are brought forward, which have been taken into consideration or adoption in practice. As a result, the production yield is promoted, and a large amount of expenses of testing and die trial-manufacture are saved.
