Abstract: The closed-cell Zn-22Al composite foams reinforced by 3 vol.% Al2O3 short fibers were fabricated with melt foaming method using CaCO3 as blowing agent. The distributions of the short fibers in the composite foams were observed by scanning electron microscopy (SEM) and the compressive properties of the composite foams were investigated in quasi-static condition. The compression test indicated that Zn–22Al/Al2O3 composite foams show better compressive properties than Zn–22Al alloy foams. The compressive curves of the composite foams exhibit a smooth and no dentate collapse plateau region; the compressive yield stress and energy absorption capacity of the composite foams increase more rapidly than those of Zn–22Al alloy foams with increasing density.
