This presentation will summarise the mechanical properties and microstructure of a Ti-3Al-2.5V alloy reinforced with 10% titanium boride particulate. The increased availability of titanium alloy powders in combination with recent developments in the Powder Metallurgy manufacturing process have led to the production of a stiff, fatigue resistant and ductile material that shows significant property benefits over conventional titanium alloys, such as Ti-10V-2Fe-3Al. The likely influence of the titanium boride particulate on density and wear characteristics will also be discussed. Secondary processing routes such as extrusion and forging will be reviewed to demonstrate the potential opportunity for cost-effective manufacturing of final components through near-net-shape processing.
