HIGH-TEMPERATURE DAMPING CAPACITY AND DYNAMIC YOUNG’S MODULUS OF AZ91D/FLY ASH COMPOSITES
RÉSUMÉ
AZ91D Mg alloy, reinforced with fly-ash cenospheres (FAC), composites were prepared by the stirring method. The effects of FAC particle size and tested frequency on the high-temperature damping capacity and dynamic Young's modulus of the composites were discussed. The results show that the FAC particles distributed homogeneously in the Mg alloy matrix and some new phases were found. The composites with the FAC of size 146 µm were of the highest damping capacity for all tested frequencies at a high temperature, while the highest dynamic Young›s modulus was attained in the composites with FAC of size 83 µm. Therefore, the composites with required damping capacity and mechanical property can be obtained by selecting the scale of reinforcement particle.
