The role of silicon carbide particles in stabilizing aluminum foam in batch type gas injection foaming process

Composite aluminum foams reinforced with SiC particles were manufactured by injecting gas into the liquid. Microstructure and mechanical behavior of the Al/SiCp foam were investigated by scanning electron microscopy and compression test. The results show that the both cell size and wall thicknesses augmented with increasing SiCP content while the Plateau border size decreased. With greater SiCp content, plateau stress was larger but maximum plateau strain was lower. The stress-strain curve exhibited serrations in the plateau region.
