Study on Fabrication, Defects and Compression Properties of Al Foams at Different Foaming Temperatures

摘要：

Using Al powder as thickening agent and CaCO3 powder as foaming agent, Al foams with above 85％ porosity, pore sizes between 1 mm and 4mm and relatively uniform pore structure have been fabricated by melt foaming method at different foaming temperatures. Meanwhile, the paper researched the effect of foaming temperature on foaming effect and analyzed the defects in Al foams. At last, compression test were taken in order to investigate the mechanical properties of aluminum foams. The results showed that pore structure, pore distribution and compression properties of Al foams fabricated at 720℃ were much better than that fabricated at lower temperature.
