Abstract: The microstructure and mechanical properties of TC11 titanium alloy after general and special forging and different heat treatment processes were analyzed. The results show that basket weave microstructure constituted of a small amount of equiaxed α phase, thin lath α phase and β phase could be got after special forging, and the mechanical properties were obviously superior to that of general forging. Basket weave microstructure which was made up of 12vol% equiaxed α phase, lath α phase and β phase with a ratio of width and length could be got in TC11 titanium alloy by special forging combining with high temperature homogenization and double annealing treatment, and the excellent strength and toughness were got.
