摘 要: 研究了泡沫Al7Si0.45Mg合金的压缩性能、吸能率,压缩后试样在空气中的流通能力,测试了其吸声和隔声性能,讨论了试样原始孔隙率对上述性能的影响,以及它们之间的相互关系. 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.
