Ti2B

Ti2B is an intermetallic compound in the titanium-boron system, forming a hard ceramic-like phase that combines titanium's lightweight properties with boron's reinforcing effects. It is primarily encountered as a reinforcing phase in titanium matrix composites and as a constituent in titanium alloys designed for high-temperature and wear-resistant applications. Engineers select materials containing Ti2B when extreme hardness, elevated temperature stability, and lightweight design are critical—such as in aerospace turbine components, wear-resistant coatings, and advanced composite systems—though Ti2B itself is typically a secondary phase rather than the primary engineering material.
