METHOD FOR ESTIMATING THE ENERGY INTENSITY OF A TITANIUM ALLOY Russian patent published in 2018 - IPC C22F1/18 G01N3/60 

FIELD: metallurgy; measuring technology.

SUBSTANCE: invention relates to methods for estimating the energy intensity of titanium alloys by their mechanical properties and the determination, based on the obtained values, of the suitability of these alloys for the production of elastic elements. Perform the definition of parameters σ_0.2/σ_B, and as the optimum ratio of the values for estimating the energy intensity of the alloy, the following values of the ratios of the indicated parameters are chosen: τ₃²/G is more than 17; τ₃²/ρG is more than 3.7; σ_0.2/σ_B in the range of 0.89–0.96; σ_B not less than 1,500 MPa; τ₃ not less than 900 MPa, where σ_0.2 – yield strength, MPa; σ_B – ultimate tensile strength, MPa; τ₃ – maximum shear stress, MPa; G – modulus of shear, MPa; ρ – density, g/cm³.

EFFECT: technical result consists in simplifying the evaluation of the elastic properties of titanium alloys and in increasing the reliability of the estimation of the energy intensity of titanium alloys that have undergone technological deformation and heat treatment regimes.
