Electromagnetic radiation in the microwave range has been utilized for the fabrication of SiC particulates-reinforced aluminum matrix cermets. Powder mixtures with compositions ranging from 70 wt% Al - 30wt% SiC to 100 wt% Al were placed and processed under protective nitrogen atmosphere in a 750 W multimode cavity operating at 2.45 GHz. Temperatures larger than 800°C have been achieved in a time varying with the mixture composition. Microstructures and some physical properties of the composites are presented.
