The structure transformation mechanism in Ti-48Al(mole percent) intermetallic alloy was investigated when it was cooled rapidly from single a phase region. The results showed that the massive gamma was obtained by an alpha --> gamma massive transformation during the quenching process in this alloy. A large number of defects, such as anti-phase boundaries (APBs), stacking faults, microtwins and dislocations, were observed to be within the massive gamma. Studies indicate that the massive gamma nucleates with coherent interface and grows in a diffusion controlled ledge growth mechanism.
