THREE-COMPONENT ALLOYS TI-ZR-O, THEIR PRODUCTION METHODS AND THEIR CORRESPONDING APPLICATIONS Russian patent published in 2022 - IPC C22C14/00 C22F1/18 

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy, namely to a three-component alloy of titanium-zirconium-oxygen; it can be used in medicine, in the transport industry, or in the energy industry. The three-component alloy of titanium-zirconium-oxygen (Ti-Zr-O) contains from 83 to 95.15 wt.% of titanium, from 4.5 to 15 wt.% of zirconium, and from 0.35 to 2 wt.% of oxygen, wherein it is capable of forming single-phase material consisting of a stable and homogenous α-solid solution with a structure of a hexagonal tightly packed (HTP) grate at a room temperature. A method for thermomechanical processing of the alloy of titanium-zirconium-oxygen (Ti-Zr-O) includes cold processing of the alloy in a recrystallized state at a room temperature with a pressing degree from 40 to 90%. In addition, thermal processing can be conducted at a temperature from 500 to 650°C during a time from 1 to 10 min.

EFFECT: high values of strength and plasticity of an alloy are provided, as well as excellent biocompatibility of the alloy.
