ABSTRACT:
A titanium alloy has greatly increased specific strength and increased thermostability. The alloy consists of a titanium matrix in which fibrous dispersoids are formed in situ. The dispersoids are rod and/or plate shaped and have a diameter or depth of about 0.1-0.5 microns and an aspect ratio of about 5-10. A typical alloy has the composition A-X where A is titanium or titanium alloy and X is boron, carbon, nitrogen, mixtures thereof, or mixtures with silicon.
