Evolution of Al Alloy Melt Foam Pore Structure in Foaming Process


Article Preview

A study was carried out to understand the relationship between the pore structure’s evolution of Al alloy melt foam and its preparation variables, which include decomposition properties of titanium hydride, the stirring foaming time and the holding foaming time. The results show that the foaming process of Al alloy melt can be inferred by the relation curves of decomposition quantity of titanium hydride and time at a specific temperature. The porosity of Al alloy melt during stirring foaming period is kept constant while the pore number increases and pore diameter decreases, which is a new method of fabricating Al alloy foam with a relatively low porosity and small pore size.
