摘要：

Cenospheres in the range of 30-50 vol.% were used as space holders for making syntactic aluminum foam having density 1.5-1.9 gm/cc using stir-casting technique. The synthesized syntactic foam ( SF) was characterized in terms of microstructures, hardness and compressive deformation behaviour. It was noted that the SF behaves like a high strength aluminium foam under compressive deformation exhibiting. at plateau region in the stress-strain curves. The plateau stress of SF decreases with cenosphere volume fraction vis-a-vis porosity following a power law relationship. But, the densification strain increases linearly with cenosphere volume fraction. (C) 2008 Elsevier Ltd. All rights reserved.
