The degree of spatial interconnection of the Mg17Al12 (beta phase) intermetallic in a Mg-9Al-1Zn alloy was assessed through senal sectioning at the centre and near a corner in a casting cross section The three dimensional reconstructions showed that the intermetallics were profusely interconnected forming a scaffold like network over the entire cross section but especially near the casting surface The scale and degree of the interconnection appeared determined by the local concentration of large dendritic grains injected from the shot sleeve The volume fractions of intermetallics obtained through the 3D reconstruction indicated a higher content of p phase at the corner regions in comparison with the core The volume fractions obtained by FIB were consistent with theoretical and experimental values obtained using other techniques (C) 2010 Elsevier Inc All rights reserved
