摘要(Abstract)：

采用粉末冶金工艺,分别制备了单一粒径TiB_2颗粒和混杂粒径TiB_2颗粒的TiB_2/Cu复合材料,研究了TiB_2颗粒混杂(2μm+50μm)增强对TiB_2/Cu复合材料微观组织和性能的影响。结果表明:在TiB_2颗粒总含量一定的条件下,与单一粒径TiB_2颗粒增强TiB_2/Cu复合材料相比,TiB_2颗粒混杂增强TiB_2/Cu复合材料的综合性能明显提高;当2μm与50μm TiB_2颗粒混杂配比为1∶2时,TiB_2/Cu复合材料综合性能最佳,硬度和导电率分别为69 HB和85.3%·IACS,相对于2μm单一粒径TiB_2颗粒增强TiB_2/Cu复合材料的硬度和导电率分别提高了12.2%和4.8%;TiB_2颗粒混杂粒径TiB_2/Cu复合材料的增强作用来源于获得了均匀致密的微观组织,不同粒径TiB_2颗粒在铜基体中更加弥散分布,使得混杂粒径的TiB_2颗粒协同增强铜基体作用更加明显,综合性能明显提高。
