陶瓷颗粒增强金属基复合材料已成为热管理新材料研究和开发中最具吸引力的材料。本文采用Al-Ti-B_4C体系，通过燃烧合成和热压烧结的方法成功制备了体积分数为40- 60%的TiC_x-TiB_2/Al复合材料。研究了TiCx-TiB 2含量对复合材料显微组织和压缩性能的影响。研究了TiCx-TiB 2/Al复合材料的磨粒磨损行为和热物理性能，并与TiCx/Al复合材料进行了比较。TiCx-TiB 2/Al复合材料的压缩性能、磨粒磨损性能和热物理性能均优于TiCx/Al复合材料，表明TiCx-TiB 2/Al复合材料更适合作为热沉材料。
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. % TiCx-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 TiCx-TiB2 content on the microstructure and compression properties of the composites was investigated. Moreover, the abrasive wear behavior and thermo-physics properties of the TiCx-TiB2/Al composite were studied and compared with the TiCx/Al composite. The compression properties, abrasive wear behavior and thermo-physics properties of the TiCx-TiB2/Al composite are all better than those of the TiCx/Al composite, which confirms that the TiCx-TiB2/Al composite is more appropriate for application as a heat sink.
