چکیده انگلیسی
The dynamic recrystallization (DRX) behavior of Ti-6Al-2Zr-1Mo-1V alloy was investigated at deformation temperature of 1000-1100 °C and strain rate of 10â3 â1.0 sâ1 by using compression test. The results show that discontinuous dynamic recrystallization (DDRX) is the predominant recrystallization mechanism at temperature higher than 1050 °C and strain rate lower than 0.01 sâ1. Meanwhile, continuous dynamic recrystallization is the main mechanism observed at temperature below 1050 °C and strain rate above 0.01 sâ1, mixed with a few DDRX grains. In addition, decreasing strain rate and increasing deformation temperature are found to facilitate the progress of DRX and refinement of grains in the Ti alloy in β forging process.
