Abstract:

The model of dynamic recrystallization of Ti-6Al-3.5Mo-1.5Zr-0.3Sihas been developed based on experimental data and implemented in QForm FEM code. Kinetics of dynamic recrystallization was simulated by Johnson-Mehl-Avrami-Kolmogorov equation. Effect of aging time (1-6 h) and temperature (450-650 °C) on mechanical properties has been experimentally studied. The model of heat treatment of Ti-6Al-3.5Mo-1.5Zr-0.3Si has been developed and implemented in QForm FEM code. The model is capable to predict phase compositionand hardness during and after arbitrary heat treatment within studied range.It was found that the highest hardness of Ti-6Al-3.5Mo-1.5Zr-0.3Si can be obtained by aging during 4-6 hours at 550 °C after solution treatment at 960 °C.
