Abstract:Two powder metallurgic methods of manufacturing TiAl based alloy sheet, including elemental powder metallurgy and pre-alloying powder metallurgy, are briefly reviewed. And the fabricating processes and materials properties of elemental powder metallurgy, elemental foil powder metallurgy, hot rolling of pre-alloyed powders, physical vapor deposition and plasma spraying are introduced. Meanwhile, the process characteristics and prospects for these techniques are also described.
