| 摘 要： | 探讨了用粉末冶金法,采用常规的冶金加工设备和工艺,制造SiC颗粒增强纯铝基复合材料的可行性;研究了不同SiC含量铝基复合材料的显微组织和力学性能.结果表明:SiC颗粒与纯铝粉混合、加压、烧结制备的复合材料,组织致密,增强颗粒分布均匀;随SiC体积百分含量增加,复合材料的强度、硬度明显升高;SiC体积面分含量小于20×10~(-2)时,塑性不降低;复合材料的拉伸断口为解理与韧窝混合断裂.

| Abstract: | The feasibility of using conventional metallurgical working equipment and technology fabricate silicon-carbide particulate (SiC) reinforced pure aluminum matrix composites made by powder metallurgy method is investigated. The microstructure, mechanical and physical properties of composites containing various SiC, concentration are also researched. The results show that the microstructure of composites is densified and the particulates distribute uniformly. The strength and hardness greatly raise with the SiC, concentration increase. The plasticity is not decrease at low SiC, concentration (<20 Vol.%). The fracture of composites assumes toughness dimple. |
