Abstract

AB STRACT
A method of processing a titanium aluminide intermetallic composition based on a TiAl intermetallic compound to yield a duplex microstructure containing equiaxed and lamellar morphologies of a gamma TiAl phase. The method includes hot isostatic pressing the titanium aluminide intermetallic composition in an inert atmosphere at a temperature of at least 1260 C, cooling the titanium aluminide intermetallic composition to a temperature of not less than 1120 C, heat treating the titanium aluminide intermetallie composition at a temperature of 1150 to 1200 C and then cooling the titanium aluminide intermetallic composition to room temperature. The titanium aluminide intermetallic composition exhibits the duplex microstructure following the step of cooling the titanium aluminide intermetallic composition to room temperature. The titanium aluminide intermetallic composition consists of titanium and aluminum in amounts to yield the TiAl intermetallic compound, one or more of chromium, niobium and tantalum, and incidental impurities.
