FIELD: metallurgy.
SUBSTANCE: proposed composite comprises matrix of pure titanium ≤250 nm age-hardened by thermally and chemically stable nano-sized particles of titanium carbide, boride or nitride with particle size of 2-10 nm. Hardening particles are uniformly distributed in composite volume while their fraction therein makes 0.05-0.50 wt %. Composite is obtained by mechanical alloying of pure titanium with particle size of 40-200 mcm in ball triple-action mill in atmosphere of protective gas and after-hot isostatic pressing.
EFFECT: higher strength due to higher yield point, extension limit, fatigue strength and biological compatibility.
