  • Tantalum and chromium containing titanium aluminide rendered castable by boron inoculation
    Patent number: 5098653
    Abstract: A method for providing improved castability in a gamma titanium aluminide is taught. The method involves adding inclusions of boron to the titanium aluminide containing chromium and tantalum. Boron additions are made in concentrations between 0.5 to 2 atomic percent. Fine gain equiaxed microstructure is formed from solidified melt. Property improvements are also achieved.
