Synchrotron X-ray tomography provides a unique non-destructive way of examining 3D or even 4D (3D plus time) measurements with high spatial and temporal resolution. One of such applications is in the study of dendrite formation of hcp Mg alloys, whose dendritic structures are difficult to reveal through 2D observations such as SEM or radiography, due to its complex crystal morphology in 3D. We will show how synchrotron X-ray tomography can be used to investigate dendrite formation in Mg alloys with varying alloy content (Zn, Ca and Sn) to generate different morphologies. The effect of different solutes and the solidification conditions, i.e. equiaxed and directional solidification, will be revealed and discussed. Moreover, in situ 3D studies of selected alloys during solidification and coarsening will also be covered in this presentation, allowing the study of the kinetics of phase transformations to be quantified in real time.
