采用熔体发泡法制备了不同铜含量的闭孔泡沫铝。研究了Cu元素在铸态和热处理条件下对泡沫铝准静态压缩性能的影响。结果表明：Cu元素主要以Al-Cu固溶体和AlCu3、Al6.1Cu1.2Ti2.7金属间化合物的形式分布在细胞壁基体中；同时，含铜泡沫具有比市售纯泡沫铝更高的抗压强度。另外，适当的热处理可以进一步提高含cu泡沫的屈服强度，并且在现有条件下时效处理的效果比均质热处理更明显，并对其原因进行了讨论。
Closed-cell aluminum foam with different percentages of Cu was prepared by melt foaming method.The effect of Cu element on the quasi-static compressive properties of aluminum foam was investigated, both under as-cast and heat-treated conditions. The results showed that Cu element distributed in cell wall matrix mainly in the forms of Al-Cu solid solutions and AlCu3, Al6.1Cu1.2Ti2.7 intermetallics. Meanwhile, Cu-containing foams possessed much higher compressive strength than the commercially pure aluminum foams. Additionally, proper heat treatment could further improve the yield strength of Cu-containing foams and the effect of aging treatment was more obvious than the homogenizing heat treatment under the present conditions and the reasons were discussed.
