摘要：

Closed-cell AlSi9Mg foams and SiCp/AlSi9Mg composite foams with different SiCp volume fractions were prepared successfully by means of direct foaming of melt using CaCO3 blowing agent in this paper. The compressive behaviors of these foams were studied. In comparison with the compressive stress-strain curve of AlSi9Mg foams that of SiCp/AlSi9Mg composite foams is not smooth and exhibits some serrations. At the same relative density of composite foams, the yield stress and collapse stress of the composite foams increase with increasing SiCp volume fraction. The relationship of yield stress, relative density and SiCp volume fraction of SiCp/AlSi9Mg composite foams with a given particle size was obtained. (C) 2007 Elsevier B.V. All rights reserved.
