Jepson, K.S. Lewis, G.I. Institution Royal Aircraft Establishment RAE Date 1961-09-30 Abstract 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% and E 21 x 10 (6) psi, and a consumable electrode melt of a Ti-5%AL-1.5%B sheet alloy had T.S. 63 ton/in² elongation 10% and E 20x 10 (6) psi. The notch sensitivity, fatigue strength and creep strength of alloys of the Ti-AL-B system appeared to be acceptable. 12lb consumable electrode melts of a 5% and 3%AL 1.5% alloys suggested that no difficulty in melting should be expected, though fabrication procedures will require attention.
