Dendritic growth orientations and three-dimensional morphologies of hexagonal close-packed alpha-Mg(Zn) solidification microstructures were studied in an Mg-Zn alloy with a high Zn content. Using a combination of electron backscatter diffraction and X-ray synchrotron tomography, we have demonstrated that alpha-Mg(Zn) dendrites grow with a six secondary branched structure behind the advancing dendrite tip. The crystallography of the branches and advancing dendrite is discussed. (c) 2012 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
