TITANIUM-BASE ALLOY AND PRODUCT MADE THEREOF Russian patent published in 2001 - IPC

FIELD: metallurgy more particularly titanium-base alloys intended for using as structural high-resistant material for designing power structures of aviation and cosmic engineering. SUBSTANCE: alloy comprises, wt %: Al, 4.5-6.5; Mo, 4.0-6.0; V, 4.0-6.0; Cr, 0.5-2.0; Fe, 0.5-2.0; C, 0.01- 0.6; O₂, 0.02-0.2; H₂O, 0.001-0.3; N₂O, 0.01-0.05; B, 0.01-0.6, Si, 0.01- 0.6; Nd, 0.01-0.7; and Ti, the balance. EFFECT: greater strength, higher heat resistance and plasticity in combination with high modulus of standard elasticity, at room and elevated temperatures; greater operate reliability and service life of products increased by 10-15 %and weight reduced by 15-25 %. 3 cl, 1 tbl
