Abstract: Experimental and theoretical investigation of new Al/SiC heteroparticles has been carried out. It is predicted that due to the appearance of a strong interface between Al and SiC, a composite material based on A; and SiC must have a significantly higher tensile strength than pure Al. Theoretical predictions are confirmed in the experiment. In particular, it is shown that the introduction of nano-SiC in a concentration of 10 wt.% in the aluminum matrix leads to an increase in the strength limit of the composite at room temperature to 317 MPa.

Keywords: DFT, interface, heteroparticles, mechanical properties.
