研究了Cu-Ti-B4C体系的燃烧合成过程。以Cu，Ti和B4C粉末为原料按不同的配比混料球磨，制成预制块．用热爆方式引燃，原位反应合成以TiB2和TiC颗粒为增强相的Cu基复合材料，采用DTA，XRD和SEM技术对反应过程和产物进行分析．井对反应体系进行热力学计算。结果表明：Ti＋B4C的反应是高放热反应，瞬间完成，随着体系中Cu的增加，反应剧烈程度降低，材料致密度提高，TiC和TiB2颗粒细小、均匀，与基体结合较好。
The combustion synthesis of Cu-Ti-B4C system was studied. To Cu, Ti and B4C powder as raw materials according to different mixing ratio ball milling, made of prefabricated blocks. Ignited by the thermal explosion method, the Cu-based composite material with TiB2 and TiC particles as the reinforcing phase was synthesized by in-situ reaction. The reaction process and the product were analyzed by DTA, XRD and SEM. Well thermodynamic calculation of the reaction system. The results show that Ti + B4C reaction is highly exothermic, and instantaneously completed. With the increase of Cu in the system, the severity of the reaction decreases, the material density increases, the TiC and TiB2 particles are fine and uniform, and the bond with the matrix is better.
