Abstract Microstructure and texture evolution of Ti-49.6Al-0.16Ni-0.14B alloy forged at 900℃ and then annealed at various temperatures were studied. Their texture components were accurately determined by the modified maximum entropy method (MMEM). Possible mechanisms of texture formation during deformation and annealing were proposed. A microstructure heredity characterization of deformed and annealed γ-TiAl alloy was reported.
