| Résumé | Iron is one of common impurities in 206 alloys and detrimental platelet-like iron intermetallics can easily form at high iron contents resulted from the increasing use of recycled aluminum alloys. The present work has investigated the iron intermetallics formed in Al-4.5 wt.% Cu alloy with 0.3 wt.% Fe and the effect of Mn and Si on the morphology and transformation of these iron intermetallics using thermal analysis, image analysis, differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). The results show that there are three major types of iron intermetallics according to their morphologies: platelet-like, block and Chinese script. It is observed that single addition of either Mn or Si, even at high contents, can only partially convert the iron intermetallics from platelet-like to Chinese script. All the platelet-like iron intermetallics can be transformed to Chinese script at appropriate addition of both Mn and Si with a combination of 0.3 wt% Mn and 0.3 wt% Si. |
