manufactured by powder metallurgical methods using foaming agent CaCO3 in order to enrich the foam fabrication process and promote its development and extensive application. The effects of CaCO3 and SiC volume fractions on the foaming behaviours were investigated by means of SEM and Magiscan-2A image analysis technique. The influence of SiC content on the compressive behaviour was analyzed using Gleeble......
