The properties and microstructure of P/ M  TiAl based alloy obtained from pre alloyed spherical pow
ders by HIP process were tested and analyzed. As the applications of P/ M TiAl based alloy, brazing technologies
and some typical components were introduced at the end of the article. The results show that P/ M TiAl based alloy
can be an attractive candidate material for some aerospace vehicles due to its good mechanical properties, fine microstructures and excellent oxidation resistance.
