Abstract

10wt.% of fly ash cenospheres (FAC), two kinds of particle average size (60 m and 120 m), two kinds of particles morphology (ball-milled to powder fragments and non-ball milled), were added to the AZ91D Mg alloy slurry to prepare the four kinds of magnesium matrix composites by stirring casting method. The effect of the particles integrity and particles size of FAC on the phases, microstructure and damping capacities of the composites was investigated. The XRD patterns and microstructure show that the new phases were produced. The damping measurement results illustrate that with the particles size increasing, the damping capacities of the composites increase, and ball-milled FAC particles have more effective on the damping capacities than that of non-ball milled particles at both 20 C and elevated to 320 C. moreover, the particles morphology has a greater 15% impact on damping capacities than the particles size at room temperature and 8% at elevated temperature.
