LOW-MODULUS METAL-MATRIX COMPOSITE BASED ON MEDIUM ENTROPY ALLOY Russian patent published in 2023 - IPC C22C32/00 

FIELD: medical tools.

SUBSTANCE: composite materials with a metal medium entropy matrix, reinforced with titanium diboride compounds, used in the manufacture of implants for traumatology, implantology and orthopedics. Metal-matrix composite TiNbZr/TiB₂ contains as a matrix an alloy based on a medium entropy alloy TiNbZr with a titanium content of 33.3 at.%, niobium 33.3 at.% and zirconium 33.3 at.% and TiB₂ particles as reinforcing ones with an average particle size of 4 μm in an amount of 2 to 4.5 wt.%. The metal-matrix composite was obtained by vacuum-arc remelting in argon of the components of the titanium, niobium, and zirconium matrix alloy and the TiB₂ reinforcing powder.

EFFECT: provision of high yield strength 905-1010 MPa and ductility 10-50% at room temperature, depending on the content of the reinforcing component TiB₂.
