TITANIUM-BASE HEAT RESISTANT ALLOY Russian patent published in 1995 - IPC

FIELD: heat resistant alloys. SUBSTANCE: alloy has, wt.-% aluminium 6.3-7.0; zirconium 3.5-4.5; tin 2.2-3.5; niobium 0.5-1.5; molybdenum 0.4-1.0; silicon 0.1-0.2; carbon 0.02-0.1; oxygen 0.05-0.12 at the total content of aluminium and tin 9.2-9.7% and silicon and oxygen 0.22-0.25% and titanium the rest. Strength limit of proposed alloy is more that known one by 15-20 kgf/cm² at 20 C and 7-10 kgf/mm² at 550 C. Alloy shows increased specific strength at indicated temperatures. EFFECT: enhanced quality of proposed alloy. 1 tbl
