Abstract
A method is for producing a TiAl-based intermetallic sintered compact. The method includes mixing Ti powder, Al powder, and a binder to yield a mixture; molding the mixture into a molded product having a predetermined shape with a metal injection molder; placing the molded product in a preliminary sintering die having a storage space inside; performing sintering at a predetermined preliminary sintering temperature to produce a preliminary sintered compact; releasing the preliminary sintered compact from the preliminary sintering die; and performing sintering at a sintering temperature higher than the preliminary sintering temperature to form the TiAl-based intermetallic sintered compact.
