Abstract:

By using CaCO3 as the “blowing agent”, Zn-(10-50) wt% Mg alloy foams with close-pore structure were fabricated by the powder metallurgical route. The key of successful foaming is Mg addition and the proper sintering treatment, which lead to the formation of intermetallic compounds and can make the gas release reaction between Mg melt and CaCO3 happen the during foaming process.

Key words: Zn-Mg alloy foam, CaCO3, Powder metallurgy, Thermal analysis
