“…Marie-Aline VAN ENDE, 1,2) Muxing GUO, 1) Joris PROOST, 2) Bart BLANPAIN 1) and Patrick WOLLANTS The phenomena taking place at the early stage of Al deoxidation were investigated with specific attention on the formation of Al 2 O 3 inclusions. In a quartz tube, Al was exposed to liquid Fe containing different amounts of dissolved oxygen (O) for 1, 5, 30 and 60 s. In this paper, quenched microstructures of the diffusion couple were examined to identify the interactions and the nature of the phases at the experimental temperature.…”
