TITANIUM-BASED ALLOY Russian patent published in 1994 - IPC

FIELD: metallurgy. SUBSTANCE: 5.7-6.7 aluminium; 2.8-3.8 molybdenum; 0.7-1.65 tin; 0.7-1.65 zirconium; 0.1-0.3 silicon; 0.05-0.15 iron; 0.01-0.08 carbon; 0.005-0.04 nitrogen; 0.05-0.15 oxygen; and titanium, the balance, the Al+Sn+Zn+Si/Mo to Me ratio being 2.5-2.85. The claimed alloy is superior over that known in the art by at least 15 % in prolonged strength and a prolonged service life of 5000 hr, at least 10% in low-cyclic fatigue, and by 40% in crack resistance. EFFECT: improved properties of the alloy. 2 tbl
