Mg-Al-Zn alloy foam with a closed-cell structure was fabricated using CaCO3 as the blowing agent via a powder metallurgical approach. The foam possesses higher compressive strength than other alloy foams.
Mg-Al-Zn alloy foam with a closed-cell structure was fabricated using CaCO3 as the blowing agent via a powder metallurgical approach. To ensure successful integral foaming, the following two principles should be used: the foamable precursor melting temperature should be lowered, the liquid fraction of the precursor should be higher than 30 wt% within 5 degrees C when the precursor starts to melt, and the melting temperature range should be less than 110 degrees C. The compression property of cellular Mg80Al19Zn1 alloy foam was examined, and the results showed that the foam possesses higher compressive strength than the other Mg/Mg alloy foams.
