Abstract
Compressive properties were investigated for the as-cast and T6 heat-treate d AZ91 Mg and SG91A Al foams with open-cell structure. The foams showed an elastic region at an initial stage, then a plateau region with a nearly con stant flow stress to a large strain of about 60%, and finally a densificati on region where the stress increased rapidly. The relative stress of the as -cast foams was higher than that of the T6 foams, taking into consideration the influence of the relative density. (C) 2000 Elsevier Science S.A. All rights reserved.
