| Abstract: | In this paper, recent developments in the use of powder metallurgy for TiAl intermetallics are reviewed in terms of powder preparation, forming, sintering and heat treatment. Some sintering methods are briefly introduced including hot isostatic processing, self-propagation high-temperature synthesis, powder injection molding and spark plasma sintering, Advantage and limitation of each techniques are also described. In addition, further research direction is pointed out. |
