| Abstract: | The compressive property and energy absorption ratio of foamed Al 7Si 0.45Mg alloy and the permeability of compressed foamed Al 7Si 0.45Mg alloy in air are studied. The coefficient of the sound absorption and the sound insulation of compressed foamed Al alloy in air are measured. The influence of original porosity of foamed alloy on the above mentioned properties is discussed. |
