Abstract

Metal matrix composites reinforced with ceramic particles have become the most attractive material in the research and development of new materials for thermal management applications. In this work, 40-60 vol. % TiC_x-TiB₂/Al composites were successfully fabricated by the method of combustion synthesis and hot press consolidation in an Al-Ti-B₄C system. The effect of the TiC_x-TiB₂ content on the microstructure and compression properties of the composites was investigated. Moreover, the abrasive wear behavior and thermo-physics properties of the TiC_x-TiB₂/Al composite were studied and compared with the TiC_x/Al composite. The compression properties, abrasive wear behavior and thermo-physics properties of the TiC_x-TiB₂/Al composite are all better than those of the TiC_x/Al composite, which confirms that the TiC_x-TiB₂/Al composite is more appropriate for application as a heat sink.
