BLANK FOR MANUFACTURING ELASTIC ELEMENTS OF A TITANIUM-BASED ALLOY Russian patent published in 2019 - IPC C22C14/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, namely to the field of titanium-based functional metal alloys, possessing increased strength, elasticity and plasticity. Blank for manufacturing elastic elements of a titanium-based alloy containing, by mass %: aluminum – 3.85–4.05, molybdenum – 4.5–5.5, vanadium – 5.05–5.5, iron – ≤ 0.5, carbon – ≤0.1, hydrogen – ≤ 0.015, oxygen – ≤ 0.15, nitrogen – ≤ 0.05, silicon – ≤ 0.15, zirconium – 0.35–0.5, titanium – the rest. At the same time, titanium has a uniform finely dispersed microstructure with a grain size of 1–5 mcm, on the boundaries of which globular particles of the primary α-phases are located. Energy intensity of the blank by parameter τ²/G is more than 20, and by parameter τ²/ρG – more than 4.7, where τ – the greatest tangential stress, MPa, G – shear modulus, MPa, ρ – density, g/cm³. Alloy is characterized by high values of the ultimate torsional strength and ultimate tensile strength in the temperature range from 20 to 350 °C. Blank for manufacturing elastic elements has a high energy intensity.

EFFECT: increase in the safety and reliability of the elastic elements.
