METHOD FOR PRODUCING STRENGTHENED METAL MATRIX COMPOSITE BASED ON MEDIUM-ENTROPY ALLOY Russian patent published in 2024 - IPC C22C1/10 C22F1/18 C22C30/00 

FIELD: powder metallurgy.

SUBSTANCE: method for producing a strengthened metal matrix composite based on a medium-entropy alloy relates to the field of powder metallurgy, in particular to the production of composite materials with a metal medium-entropy matrix, strengthened with titanium diboride compounds. The method involves producing a TiNbZr/TiB₂ metal matrix composite by vacuum-arc remelting at an operating temperature of 3500°C for 60 minutes of high-purity titanium, zirconium and aluminium, taken in the following percentages: 33.4 at.% titanium, 33.3 at.% niobium, 33.3 at.% zirconium and further adding 0.7 wt.% TiB ₂ from the total weight of the TiNbZr matrix alloy. Next, sheet rolling of the resulting TiNbZr/TiB ₂ metal matrix composite is carried out at room temperature to a total degree of deformation of 80% with compression per pass~ 200 µm, equal to the degree of 8% deformation.

EFFECT: production of implants for use in traumatology, implantology and orthopaedics.
