COMPOSITE MATERIAL WITH THE STRONG METAL MATRIX AND STRENGTHENING PARTICLES OF TITAN CARBIDE AND THE METHOD OF ITS MANUFACTURING

摘要

FIELD: technological processes.;SUBSTANCE: group of inventions relates to the production of a composite material comprising the metal matrix of an aluminum alloy and reinforcing particles of titanium carbide. Mechanical alloying of the mixture containing titanium powder and nanodiamonds is carried out at the ratio, which is equal to (47.867÷52):(12.0107), and the powder of the matrix components, with the provision of synthesis of titanium carbide particles in the matrix. Powder of the matrix components in the form of an aluminum powder and the powder of at least one component selected from the range, which consists of copper, magnesium, lithium, nickel, chromium, zinc, and manganese are used. First, during 5–50 % of the total mechanical alloying time, the initial mixture with the matrix content of 5–50 WT% of the total processed material, after which the matrix components are added in the amount of at least 0.05 parts by weight of the original mixture and not more than 10 parts by weight of the original mixture and mechanical alloying is carried out until the processing is complete. Resulting composite material comprises the aluminum alloy matrix and titanium carbide particles in the amount of 3–30 WT%, where at least 90 % of titanium carbide particles are nano-sized.;EFFECT: increased strength is provided.;8 cl, 2 ex
