Abstract
AbstractThe possibility of applying globular carbon for reinforcing the aluminum matrix when using mechanical alloying to produce composites was shown by investigating specific properties of chemical interaction of nanocarbon with the aluminum matrix. The structure of the initial particles of globular carbon and composite granules was studied. Mechanical alloying can significantly crush the initial particles of globular carbon. The use of the method of differential scanning calorimetry allowed the temperature of the start of the reaction between globular carbon nanoparticles and aluminum matrix with the formation of aluminum carbide to be determine as 320 °C–350 °C. Aluminum matrix composites with reinforcing particles of globular carbon can be used up to these temperatures without risk of the formation of aluminum carbide.
