Abstract
Deformation behavior of an Al2O3 foam with an open-cellular structure was investigated by compressive tests. The variation in flow stress with strain was significantly large and there was no densification region. Breakage of the columns is responsible for the large variation in flow stress with strain and no densification region. The relative stress of the Al2O3 foam was lower than the value predicted by Gibson and Ashby. This is probably because of the high degree of cracking in the columns and the presence of partial closed-faces.
