Simulation of microstructure evolutions of VT6 alloy during isothermal forging using Deform software
The article contains results of modeling of bi-modal microstructure evolution of VT6 alloy during isothermal forging. The model of recrystallization based on dislocation approach to nucleation and growth of nuclear was made to calculate recrystallization processes of the secondary alpha phase. The globularization pro-cess of lamellar alpha phase was calculated with assumption of diffusion-control migration of beta-phase bound-ary due to grain boundary diffusion of vanadium atom. The theoretical results were compared with experimental one.
