High modulus titanium alloys based on the titanium-boron system

The Young's modulus and strength of titanium were increased by the incorporation of TiB particles in a matrix of alpha, the ductility and impact strength decreasing with increase of boron content. Ternary alloys in the Ti-Al-B system showed interesting properties. A laboratory melt of Ti-7%AL-1.5%B bar alloy had T.S. 74 ton/in², elongation 9%...
