In this paper, the fabrication of TiAl alloy powders by high-energy ball milling and heat preservation at low temperature and high vacuum using titanium powders of 30 micron and aluminum powders in the size of 9-12 micron. After being heated under the different time and temperature, the alloying of milled and heated powders of titanium and aluminum were investigated. The results show that the alloy powders with the main intermetallic compounds of TiAl and a small quantity of aluminum tri- titanium can be obtained through one hour high-energy ball milling and preserving heat 2 hours at 500°C, 3 hours at 600 °C in high vacuum. Furthermore, the transitional alloy phase Al2Ti was formed at 550 °C~600 °C, and it has an effect on the density of Ti-Al alloy powders in the diffusion synthesis. The fabrication of TiAl alloy powders with different density by sintering diffusion at low temperature and high vacuum is effective.

Ti/Al(Ti-50at.%Al) composite powders were prepared by high-energy ball milling followed by reaction sintering heat treatment at 550°C ~ 650°C for 2 hours. Mechanical alloying of TiAl had been performed in a high energy plant ball after different milling times and pre-sintered at different temperatures. The particle sizes of Ti/Al powders were analyzed by scanning electron microscopy (SEM). X-ray diffraction (XRD) analysis was performed for microstructural characterization. The results show that microstructural and morphological changes of high energy milled powder are studied as a function of milling time. Over 600°C TiAl powders are completely alloyed by being sintered at different temperatures. The powders are mainly composed of γ-TiAl as well as a small amount of AlTi3. The TiAl alloy powders of high energy ball mill/2h and sintered at 650°C/2h get plasma spheroidization. Spheroidizing powders with fine texture, γ-TiAl and AlTi3phase, particle size of 10~40μm are obtained.
