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

FIELD: instrument engineering.

SUBSTANCE: invention relates to the field of ultrasonic technological systems for various purposes and can be used to create an alloy for the manufacture of ultrasonic electrodes having a high service life. Alloy based on titanium contains, wt. %: aluminum 5.8-8.0, molybdenum 2.8–3.8, zirconium 2.1–3.0, silicon 0.20–0.40, iron ≤ 0.3, oxygen ≤ 0.15, carbon ≤ 0.1, hydrogen ≤ 0.015, nitrogen ≤ 0.05, titanium – the rest. Alloy has a uniform, finely dispersed microstructure with globule size (0.5–5.0) mcm, containing equiaxial α-phase in the (40–80) % amount in the transformed βmatrix without a continuous network α-phase at the boundaries β-green, and the ultimate tensile strength is not less than 1200 MPa with the ratio of the parameters σ_0.2/σ_B not less than 0.9, where σ_0.2 – yield strength, MPa, σ_B – ultimate strength, MPa.

EFFECT: extended ultra-frequency range of the waveguide in the region of higher frequencies.
