    • Titanium alloy parts were prepared by metal injection molding, binder was removed from the parts by solvent debinding process, and the brown parts were densified in vacuum atmosphere. The as-sintered specimens were treated through hot-isostatic pressure at 960℃ and 140 MPa, and titanium alloy compacts were annealed at 720-760℃ for 1-1.5 h. SEM observations showed that the titanium alloy had a uniform dial microstructure with many equiaxed a grains and a little β grains. XRD results indicated that Ti3Al phase was found in the alloy when the annealing temperature was higher than 800℃.
