Powder metallurgical (PM) route is one of the methods for metal foam fabrication. In this paper, we report the fabrication of Zn alloy foams with 0~50wt.% Mg via powder metallurgical approach by using CaCO3 as the blowing agent. The fabrication process included 5 steps: powders mixing, cool-pressing, heat treatment, hot-pressing, foaming and cooling. The effects of Mg addition, foaming temperature on the foaming process were discussed. Finally, the compressive behavior of Zn alloy foam was evaluated.
