3D images of the secondary phases were obtained using the Robo-Met.3D® serial sectioning system. High contiguities between Si, aluminides and Mg2Si were observed in both alloys without and with ultrasonic melt treatment (UST). Mg2Si phases were observed mainly adjacent to the eutectic platelets of Si or aluminides.
