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镁基复合材料，研究了其机械性能和阻尼性能。结果表明，增强物的加入提高了纯镁的强度，但同时也减小了复合材料阻尼的应变振幅效应，从而降低了其阻尼性能。研究证明此镁基复合材料的阻尼行为可按Ｇ－Ｌ位错阻尼理论解释，与纯镁一致。

Abstract: A new kind of composite with the matrix of pure magnesium was fabricated and its mechanical properties and damping capacity were studied in this paper. It was found that the strength of the magnesium matrix composite was improved largely compared with that of pure magnesium, however, its damping capacity dependent on strain amplitude was decreased due to the addition of the reinforcements. It was also proved that the effective damping mechanism in the magnesium matrix composite was G L dislocation damping model, the same way as that in the pure magnesium metal.
