Abstract

Recycling of aluminium alloys is gaining significant attention due to its economic and environmental benefits. However, close loop recycled aluminium alloys can be adversely affected by impurities and alloying elements present in the recycled feedstock. In this study, the influence of three composites, namely alumina (Al2O3), ferric oxide (Fe2O3), and manganese (Mn), on the properties of recycled aluminium taldon scraps was investigated to enhance the tensile behaviour of the alloys. The effects of these composites on the mechanical properties, microstructure, and corrosion behaviour of the recycled aluminium alloys were evaluated through experimental characterization techniques. The results showed that the addition of these composites had a significant influence on the properties of recycled aluminium alloys, providing insights into the potential for improving the performance of recycled aluminium alloys through composite additions. The addition of Al2O3 enhanced the tensile strength by 44.18 % and the variation can be attributed to the strengthening of the dendritic zones by the formation of α-Al.

氧化铝、氧化铁和锰复合材料对再生铝合金性能的影响

铝合金的回收利用因其经济和环境效益而备受关注。然而，回收原料中的杂质和合金元素会对闭环回收铝合金产生不利影响。本研究调查了氧化铝 (Al2O3)、氧化铁 (Fe2O3) 和锰 (Mn) 这三种复合材料对回收铝塔尔登废料性能的影响，以增强合金的拉伸性能。通过实验表征技术评估了这些复合材料对再生铝合金的机械性能、微观结构和腐蚀行为的影响。结果表明，添加这些复合材料对再生铝合金的性能有显著影响，为通过添加复合材料提高再生铝合金性能的潜力提供了启示。添加 Al2O3 后，拉伸强度提高了 44.18%，这种变化可归因于α-Al 的形成强化了树枝状区。
