Abstract The rapidly solidified powder of Ti-34Al-2Mn alloy was produced by gas atomization. The typical value of the size of RS powder is 27μm. X-ray diffraction results show that the microstructure of RS powder consists of major α_2-phase and minor γ-phase. On the optical micrograph there are equiaxed and dendritic grains. After annealing at 900℃, 2 h in vacuum, most of α_2-phase transformed into γ-phase and the microstructure becomes finer.

Key words: rapid solidification TiAl alloy microstructure
