ABSTRACT:
A method for providing improved ductility in a gamma titanium aluminide is taught. The method involves adding inclusions of boron to the titanium aluminide containing chromium, carbon, and niobium and thermomechanically working the casting. Boron additions are made in concentrations between 0.5 and 2 atomic percent. Fine grain equiaxed microstructure is found from solidified melt. Property improvements are achieved by the thermomechanical processing.
