abstract A porous skeleton of TiC carbide was successfully fabricated by combustion synthesis ignited in a microwave field. The synthesizing temperature has been remarkably affected by the time of ball milling or positioning in a single mode microwave reactor. The combustion products were characterized by XRD and SEM investgatons. To moderate the reaction and avoid the explosion mode, an aluminium powder was added to the mixture. The prepared TiC, Al-Ti-C skeletons were next infiltrated with an AlSi12 aluminium alloy by the squeeze casting method. The composite materials exhibited a relatively homogeneous microstructure with low porosity.
