<p>A titanium-based composite material which comprises a matrix containing a titanium (Ti) alloy as a main component and, dispersed in said matrix, titanium compound particles and/or rare earth compound particles, characterized in that said matrix contains 3.0 to 7.0 wt. % of aluminum (Al), 2.0 to 6.0 wt. % of tin (Sn), 2.0 to 6.0 wt. % of zirconium (Zr), 0.1 to 0.4 wt. % of silicon (Si) and 0.1 to 0.5 wt. % of oxygen (O), and, said titanium compound particles account for 1 to 10 vol % and said rare earth compound particles account for 3 vol % or less. The titanium-based composite material having the aforementioned composition provides a titanium-based material being excellent in heat resistance, hot workability, specific strength and the like.</p> |
