Abstract

For the first time prepared successfully mechanisms and pore melt can affect CaCO^AZ91 (MgA19Znl) and AM60 (MgA16) Mg alloy foams with homogeneous pore structures were via melting foaming method by using CaC03 powder as blowing agent. The possible foaming structures o f these Mg alloy foams were discussed and investigated. The results show that Mg alloy decomposition behavior and AZ91 Mg alloy is relative easy to be foamed into metal foam with high porosity and big pore size.
