ABSTRACT:
A titanium-based microcomposite material includes first and second constituents. The first constituent is titanium or a titanium-based alloy. The second constituent is about 1% to about 50% by volume titanium aluminide. The microstructure of the microcomposite material includes smaller portions of titanium aluminide uniformly distributed among larger portions of titanium or a titanium-based alloy. The microcomposite material has improved elevated temperature properties and an increased strength-to-weight ratio.
