Al-metal matrix composites (AMMCs) reinforced with diverse volume fraction of SiC nanoparticles were synthesized using microwave sintering process. The effects of the reinforcing SiC particles on physical, microstructure, mechanical, and electrical properties were studied. The phase, microstructural, and surface analyses of the composites were systematically conducted using X-ray diffraction (XRD), scanning electron microscope (SEM), and surface profilometer techniques, respectively. The microstructural examination revealed the homogeneous distribution of SiC particles in the Al matrix. Microhardness and compressive strength of nanocomposites were found to be increasing with the increasing volume fraction of SiC particles. Electrical conductivity of the nanocomposites decreases with increasing the SiC content.
采用微波烧结工艺合成了不同体积分数碳化硅纳米颗粒增强的铝基金属基复合材料（AMMCs）。研究了增强碳化硅颗粒对物理、微观结构、力学和电学性能的影响。分别使用X射线衍射（XRD）、扫描电子显微镜（SEM）和表面轮廓仪技术对复合材料进行了相、微观结构和表面分析。微观结构检查表明碳化硅颗粒在铝基体中分布均匀。发现纳米复合材料的显微硬度和抗压强度随着碳化硅颗粒体积分数的增加而增加。纳米复合材料的电导率随着碳化硅含量的增加而降低。
