摘要：

In this study, steel meshes with various opening ratios phi were used to shape aluminum foams during precursor foaming. The effect of phi on the heating rate and shape of the obtained aluminum foams was investigated. It was found that steel meshes with various opening ratios can be used to shape aluminum foam. There is no significant effect on the pore structures of the obtained aluminum foams when upward expansion is restricted during foaming, regardless of the value of phi. The meshes with higher phi clearly transfer the mesh pattern onto the surface of the aluminum foam but require a shorter foaming time. In contrast, the lower-phi meshes produce aluminum foams with a smoother surface but a longer foaming time is required.
