Notes:
Lightweight metallic foams are an attractive material having excellent energy absorptionand acoustic damping. The density of magnesium is the smallest among structural metallic materials,and is about two third of the density of aluminum. It is, however, difficult to produce magnesiumfoams by conventional process because of their chemical activity. This paper provides a novelmanufacturing process of magnesium foams. Accumulative diffusion-bonding process can producea magnesium matrix composite (preform) containing titanium hydride (TiH2) particles as a blowingagent. Foaming tests of three magnesium alloys, AZ31, AZ91 and ZA146, revealed that low solidustemperature is effective to produce fine cell morphology. Chemical composition is significantlyimportant to optimize the cell morphology of magnesium foams
