Popis: Methods for the production and application of ultrafine β silicon carbide fibers for hardening metal matrix composite materials based on Al and Mg are developed. The fundamental possible application of the fabricated fibrous silicon carbide for creating Al–SiC and Mg–SiC composites by liquid-phase stirring without additional wetting reagents under a layer of protective fluxes at the melting temperature of the matrix alloy is shown. Ultrafine SiC is found to be uniformly distributed over the composite volume. The microhardness of the sample surface increases with the silicon carbide content as compared to the initial materials and composites made from other silicon carbide modifications.
