“…It has been established theoretically and experimentally in the literature that the formation of oxides in Al-Mg alloys is dependent on the Mg content in the alloy and the melting conditions [25][26][27][28][29]. However, there is very limited information on the microstructural features of the oxides formed in liquid Al-Mg alloys due to the associated experimental difficulties [27].…”

“…This layer from 3004 #2 was ~7-8 cm thick and was much more fragmented compared with the isolated, self-contained particles observed in the dross from alloy 3004 #1. A low magnification image showing the distribution of particles within the dross layer is shown in Fig 4.10 (compare with oxide particle morphology shown in Figure 4. [8][9][10] This is exactly the progression of microstructure/phase development observed in the dross from alloy 3004 #2. Clearly, even in a low-Mg alloy such as 3004, oxidation of the molten Al is controlled by the rate at which the Mg is oxidized and thus consumed.…”

“…It was ~1 cm in diameter/length and exhibited the characteristics typical of the Al metal encapsulation described for alloy 1350 (areas of trapped Al metal are denoted by arrows in Fig 4.8 results in extremely rapid oxidation rates and, thus, extensive dross formation for these alloys. This is termed breakaway oxidation [10] and it will continue at an accelerated rate until the Mg near the surface of the melt has been depleted. At that point, the much slower oxidation of the molten Al to form α-Al 2 O 3 begins.…”
