PRODUCTION OF BORON CARBIDE BY MECHANOCHEMICAL METHOD AND INVESTIGATION OF USABILITY ON THE ALUMINIUM BASED COMPOSITE MATERIAL

In this study, boron carbide has been synthesized using boron and carbon elements. ceramic-metallic composite material produced and tested from this material. the study established two phases. at the first stage, carbon and boron elements, which 4 different ratio, are produced in inert atmosphere with mechanochemical reaction. products are sintered at 1550° c fort he formation of boron carbide crystals. at the second stage, 5 different rates of al-b4c composites prepared by making a uniform ball mill, pressed into the plate 400 mpa pressure. after al-b4c composites pressed at 600 ° c for 1 hour at atmospheric environment, their hardness measurements were carried out. at the end of the study, the sample which was sintered during 120 min in argon atmosphere, b/c ratio is 4/1 and 50% reinforced composite are chosen optimum parameters.
