Abstract
The paper presents the results of studies on the production of composites during the processing of aluminum melt based on high‑strength alloy B95 activated dispersed particles of nitrides (AlN, Si3N4, TiN), carbides (SiC, TiC), nanostructured carbon (fullerene carbon black), nitrogen‑containing components (glycine C2H5NO2, carbamide CH4N2O). The evaluation of the strength properties of the obtained composites from the activation modes of the charge with dispersed particles and the modes of heat treatment of the material is given. The possibility of increasing the strength characteristics of the casting composite by 15–20 % due to additional mechanical activation of the charge and achieving, after heat treatment, the compressive strength of 900–1050 MPa, hardness of 150–160 NV, elastic modulus of 20–25 GPa is shown.
