COLD-ROLLED STRIP FOR PRODUCTION OF CORROSION-RESISTANT EQUIPMENT COMPONENTS AND METHOD FOR ITS PRODUCTION Russian patent published in 2023 - IPC C22C14/00 C22F1/18 B21B3/00 

FIELD: metallurgy.

SUBSTANCE: materials and methods for manufacturing sheet semi-finished products from pseudo-alpha titanium alloy of the Ti-Ni-Mo system for the manufacture of corrosion-resistant equipment components. Cold-rolled strip made of pseudo-α titanium alloy of the Ti-Ni-Mo system for the manufacture of corrosion-resistant components is characterized by the fact that pseudo-α titanium alloy contains, wt.%: Ni 0.6-0.9, Mo 0.2-0.4, Fe no more than 0.3, C no more than 0.08, O₂ no more than 0.25, H₂ no more than 0.015, N₂ no more 0.03, the rest is titanium, while the strip material has a basal-prismatic texture with a predominant transverse prismatic component, the average value of the pole densities of the basal component {0001} is no more than 6.0 units, the average value of the pole densities of the prismatic components and is no more than 8.0 units, and the yield strength ratio σ_0.2 in transverse direction to σ_0.2 in the longitudinal direction is 1.0-1.1, the tensile strength ratio σ_B in the transverse direction toσ_B in the longitudinal direction is 1.0-1.07, and the alpha phase contained in the microstructure of the strip has a degree of recrystallization from 50 to 80%.

EFFECT: resulting strip has a complex of high mechanical properties and minimal anisotropy.
