The structure and the hardness of hybrid metal matrix composites with a matrix from alloy 6063 of the Al – Mg – Si system and dispersoid particles of Al2O3 and SiC are studied. At less than 5 wt.% dispersoid in the composition the distribution of particles in the matrix is uniform; at a higher content of dispersoid the particles are segregated even over grain boundaries of the matrix. The density and the hardness of the composites increase with the content of the dispersoid.

6063/Al2O3p-SiCp混合复合材料的最佳老化参数

研究了以 Al-Mg-Si 系 6063 合金和 Al2O3 和 SiC 弥散颗粒为基体的混合金属基复合材料的结构和硬度。在组合物中小于 5 wt.% 的分散质时，颗粒在基质中的分布是均匀的；在较高的分散体含量下，即使在基体的晶界上，颗粒也会分离。复合材料的密度和硬度随着分散质含量的增加而增加。
