Structure and properties of AlSiC foam

The mechanical response of composite foam AlSiC has been examined in compression and indentation. The foam has a closed cell structure and is made of aluminium matrix with SiC particles dispersed in it. The cell walls have a complex microstructure consisting of non-uniform distribution of particles, voids and cavities as well as micro-segregation and precipitates resulting from dendritic solidification. Consequently, the mechanical response is …
