Because of capability of preparation for Ti-Al based intermetallics with fine and uniformity micro鄄
structures, powder metallurgy processing method has an unique application in preparing Ti-Al based intermetallics.
Using the examples of Ti-23Al-17Nb (at%) and Ti-45Al-2Cr-2Nb-(B, W)(at%) alloy, the paper introduces
the fabrication, shaping and properties of Ti-Al based intermetallic prepared by powder metallurgy processing, and
shows a good prospect of applications in the aerospace areas.
