摘要

The evolution of microstructure in Ti-5Al-5Mo-5V-1Cr-1Fe with an initial lamellar microstructure during compression to a true strain 1.2 at 800 ℃ was established via EBSD analysis. The principal features comprised recrystallization of the β matrix and fragmentation/spheroidization of α lamellae. Angular deviations from the Burgers orientation relation (OR) and the kinetics of the spheroidization of lamellar microstructure as a function of strain were quantified. The influence of the deviation from the OR on spheroidization kinetics of the lamellar structure was interpreted.
