摘要：

Alloying additions of 0, 0.5 and 1.0 at.% W were made to Ti-48Al-2Nb-2Cr alloys for increased strength and creep resistance. The alloys were processed by both ingot metallurgy (IM) and powder metallurgy (PM) routes. Duplex and near-lamellar microstructures were produced by heat treatment. The tensile properties of the materials were examined in the temperature range 25-1000 degrees C in air. The creep properties were determined at 850 degrees C at stresses ranging from 103 to 207 MPa. The interrelationship between composition, microstructure, processing and properties are discussed.
