| 英文摘要 | Due to inherent high damping capacities of Mg, Mg-based alloys or composites can absorb enormous elastic energy, thus, can be used as damping materials playing important role in reducing vibration and noise. Spherical Mg2Si magnesium matrix composites were prepared by super-gravity method with fly ash floating beads with particle sizes of 80, 125 and 500 渭m. The microstructures and damping capacities of prepared samples were discussed. Spherical and fragment-shaped Mg2Si phases were observed in the matrix by SEM micrograph. Increasing particle size of fly ash floating beads can lead to an obviously decreasing tendency of internal friction tan 蠁 .The critical strain cr =1.9脳10-2 of -tan蠁 curve and critical temperature Tcr =150 掳C of T-tan蠁 curve for tan蠁 changing from slowly to greatly increasing. Damping peaks occur in the vicinity of strain =5.2脳10-2 in -tan蠁 curve whereas no damping peaks occur in T-tan蠁 curve. 漏 2018 The Authors, published by EDP Sciences.
