Japanese Patent JP2877999

Kind Code:

B2

Abstract:

PURPOSE:To produce an intermetallic compd. to be used as the heat and wear- resistant materials wherein a carbide and a titanium-aluminum-based intermetallic compd. are finely compounded. CONSTITUTION:The metal powders of titanium and aluminum are mechanically alloyed in an inert gas atmosphere to form the cohesive aggregates, then a lower hydrocarbon is added to the aggregates which are mechanically alloyed in a wet state, hence the metal powders react with the hydrocarbon, the excess hydrocarbon is removed from the product, and the product is pressed and sintered to produce a TiAl-based intermetallic compd. wherein the carbides are compounded. Consequently, the carbides and the titanium-aluminum-based intermetallic compd. are finely compounded, and the hardness is remarkably enhanced from the room temp. to high temp.
