Microwave Sintering of Aluminum Composite

Microwave heating has a long history in the industry, most notably in the food processing industry. Furthermore, it is used in the processing of organic and inorganic materials. This technology is increasingly being used in the manufacture of sintered composite materials. In this paper, the properties of aluminum alloy powders—microwave sintering at a temperature of 5500 C (Al–SiC–B4C)—are investigated. The influence of various Al, SiC, and B4C compositions’ mechanical and physical properties are also investigated. It is observed that as apparent density increases, the tendency to shrink during sintering appears to decrease. Boron carbide has a greater tap density (93%) than silicon carbide (90%), which is greater than the tap density of aluminum. The microhardness of the metal matrix composite increased linearly with increasing boron carbide content.
