METHOD OF ESTIMATING ENERGY CAPACITY OF TITANIUM ALLOY Russian patent published in 2018 - IPC C22F1/18 G01N3/60 

FIELD: metallurgy.

SUBSTANCE: parameter σ_0.2/σ_B is determined, and an alloy is selected: with parameter τ₃²/G more than 17, τ₃²/ρG more than 3.7, σ_0.2/σ_B within 0.89-0.96, tensile strength at break σ_B not less than 1500 MPa, maximum tangential stress at torsion is not τ₃ at least 900 MPa, fine-dispersed microstructure with globular size of 1-10 mcm martensite type with smaller substructural components on periphery with presence of discrete grains of globular particles of primary α-phase at boundaries of individual grains, where σ_0.2 is a yield point, MPA; G is a modulus of elasticity at shear, MPA; ρ density, g/cm³.

EFFECT: simplified estimation of elastic properties of titanium alloys and improved reliability of estimation of energy capacity of titanium alloys which passed technological modes of deformation and heat treatment.
