TITANIUM ALLOY AND THE METHOD OF MANUFACTURING THE CASING FOR PRODUCTS THAT EXPERIENCE CYCLIC LOADS Russian patent published in 2019 - IPC C22C14/00 C22F1/18 B21J5/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, namely to ultrasonic technological systems, and can be used to create ultrasonic electrodes having a high service life. Procurement of a waveguide of high-amplitude acoustic systems from a titanium-based alloy containing, by mass %: 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, while it has a uniform finely dispersed microstructure with a grain size of 0.5–5.0 mcm, equiaxial αphase in an amount of 40–80 % in the transformed β-matrix without a continuous grid α-phase at the boundaries β grains. Method for producing a waveguide preform, characterized in that a multi-stage forging of the preform is performed, after the third stage, repeat until the required microstructure is obtained.

EFFECT: ultra-frequency range of the waveguide is extended in the region of higher frequencies; the safety of the operation of ultrasonic waveguides is increased.
