Description: Aluminum-based composite materials reinforced with ceramic particles are of great practical interest due to their potentially high physical and mechanical properties. In this work, Al–Al4C3 composites are obtained by a hot-pressing method. Introduction of nanodiamonds into aluminum nanopowder in the amount 10 wt % leads to the formation of 15 wt % of aluminum carbide during hot pressing. It is found that composite materials with the diamond content of 10 wt % in the initial powder mixture have the microhardness 150 HV whilst the similarly hot-pressed aluminum powder without reinforcing particles shows a hardness of 75 HV. The mechanical properties of an Al–Al4C3 composite material at elevated test temperatures exceed those of commercial casting aluminum alloys.
