The rapidly solidified powder of Ti-34Al-2Mn alloy was obtained by means of ultrasonic gas atomisation (USGA) technique.The tupical size of the powder is 27 μm.X-ray diffraction results show that the powder consists of major α_2-phase and minor γ-phase.Under optical microscope both equiaxed and dendritical microstructure features were observed on RS pow- der sections.After annealing at 900 ℃/for 2 h in vacuum,most of α_2-phase transforms into γ-phase,resulting in refinement of structure.
