摘要

研究了界面反应对复合泡沫铝力学性能的影响，该复合泡沫铝是通过将332铝合金渗透到4 mm可移动NaCl空间支架和2 mm Al2O3和Al(OH)3增强球的混合物中获得的。评价了4:1、2:1和1:1 NaCl/钢筋的体积比。所得泡沫材料的孔隙率为35% ~ 48%，补强率为12% ~ 37%，具有均匀和随机分布。在Al(OH)3-基体界面处形成SiO2层，显著改善了材料的力学性能。

The role of interphase on the mechanical behavior of Al2O3/Al(OH)3 reinforced Al foams

This study focused on analyzing the effect of interfacial reactions on the mechanical properties of composite aluminum foams, which were obtained by infiltrating a 332 Al-alloy into mixtures of 4 mm removable NaCl space holders, and 2 mm spheres of Al₂O₃ and Al(OH)₃ as reinforcements. Volume ratios NaCl/reinforcement of 4:1, 2:1, and 1:1 were evaluated. Obtained foams revealed porosities between 35 and 48 %, and reinforcement contents from 12 to 37 %, with homogeneous and random distributions. The formation of a SiO₂ layer at the Al(OH)₃-matrix interface significantly improved the mechanical properties.
