The porosity of porous Al-Si alloy is 40~80% and percentage of open-cell is above 85%, bom of which vary with the fabrication process of preform.
孔隙率在40～80%，孔隙连通率在85%以上，孔隙的大小和孔隙率取决于预制块的制备工艺。

Experimental results show that the flow stresses of the aluminum foams increase with increasing strain rate, demonstrating a distinct strain rate effect in the open-cell aluminum foams.
实验结果表明，通孔泡沫铝有明显应变率效应，随应变率上升，泡沫铝流动应力提高。
