TITANIUM-BASE ALLOY Russian patent published in 1995 - IPC

FIELD: nonferrous metallurgy; specifically, titanium- base alloys applicable in manufacture of bars, blade stampings, fastenings and other components of aeronautical equipment. SUBSTANCE: titanium-base alloy has the following qualitative and quantitative composition, mas. aluminium 4.6-5.6; molybdenum 3.5-4.5; tin 0.7-1.7; zirconium 0.7-1.6; silicon 0.05-0.2; iron 0.05-0.15; carbon 0.05-0.08; nitrogen 0.003-0.04; oxygen 0.05-0.15; the balance, titanium; with (Al+Sn+Zr+Si):Mo ratio of 1.7-2.0. EFFECT: higher fatigue strength and prolonged serviceability up to failure of specimen with fracture, larger bending angle and increased ductility in cold strain. 3 tbl
