The microstructure characteristics and deformation mechanisms of a near-beta Ti-55511 alloy during thermal deformation at 860 °C and 830 °C are investigated. The results reveal that dynamic recovery (DRV) and extended continuous dynamic recrystallization (CDRX) are the primary mechanisms driving microstructure development in β matrix. At 830 °C, when the strain rate ranges from 0.001 to 1 s -1 at tenfold intervals, the grain size decreases from 480 μm to 7.26, 5.18, 4.05, and 3.79 μm, respectively, representing a decrease of an order of m...
