Analysis on Phases and Grain Evolution of TC4 Ti-Alloy in Hot Forming in Time and Space Based on Deform-3D

Abstract:

In the hot forging process of TC4 Ti-alloy large die forging two beam, the dynamic recrystallization of α phase and recovery of β phase were happened. Using Deform-3D finite element analysis software, the evolution model of grain and phase is constructed and coupled simulation is carried out, on the foundation of simulation results, the evolution law of α phase dynamic recrystallization and β phase transformation in time and space was obtained, so the optimal control of grain and phase was realized. Thus the performances of TC4 Ti-alloy will be improved and optimized, and all this will provide theoretical basis for the forging of large Ti-alloy components.
