摘　　要：制备了以纯镁为基体、以混杂碳化硅颗粒和硅酸铝短纤维为增强物的一类特殊复合材料，研究了其阻尼性能，发现镁基复合材料的强度优于纯镁，但阻尼性能却降低了，并随增强物含量增加，这种下降越大。镁基复合材料的阻尼性能与其状态关系密切，退火处理和热循环处理提高了复合材料的阻尼性能。A new kind of metal matrix composite with the matrix of pure magnesium and the reinforcements of hybrid SiC p and Al 2O 3. SiO 2f was fabricated and its damping capacity was studied in this paper. It was found that the damping capacity of the composite was lower than pure magnesium while its tensile strength was increased largely. And it was also found the annealing treatment and the heat recycling treatment could improve the damping capacity of magnesium matrix composite.
