TITANIUM-BASED ALLOY Russian patent published in 2019 - IPC C22C14/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, namely to the field of ultrasonic technological systems for various purposes, and can be used to create ultrasonic electrodes with a high service life. Titanium-based alloy containing, by mass %: aluminum – 5.8–8.0; molybdenum – 2.8–3.8; zirconium – 0.6–0.9; silicon – 0.20–0.40; iron – ≤ 0.3; oxygen – ≤ 0,15; carbon – ≤ 0.1; hydrogen – ≤ 0.015; nitrogen – ≤ 0.05; titanium – the rest. At the same time, titanium has a uniform finely dispersed microstructure with a grain size of 0.5–5.0 mcm, containing equiaxial αphase in an amount of 40–80 % in the transformed β-matrix without a continuous grid α-phase at the boundaries of β grains. Ultimate tensile strength is not less than 1200 MPa with the σ_0.2/σ_B parameter ratio of not less than 0.9, where σ_0.2 – yield strength, MPa, σ_B – ultimate strength, MPa. Ultra-frequency range of the waveguide's operation in the region of higher frequencies is expanding.

EFFECT: safety of the operation of ultrasonic waveguides is increased, as well as the quality of the work performed by ultrasonic electrodes having an increased service life in the region of the high ultrafrequency range.
