Abstract Scope In this contribution, examples are presented of how in-situ imaging methods are used in the research and development of magnesium-based grain-refined and nanocomposite materials. These illustrative results are drawn from the EC collaborative research project ExoMet (www.exomet-project.eu). The first example concerns the solidification of a Mg-Nd-Gd alloy with Zr addition to assess the role of zirconium content and cooling rate in crystal nucleation and growth by micro-focus X-ray radiography. The second example concerns the solidification of a Mg-Zn-Al alloy and its SiC-containing nanocomposite material to reveal the influence of particle addition and cooling rate on microstructural development by synchrotron X-ray tomography. The third example concerns the (partial) re-melting and -solidification of Elektron21/AlN and Elektron21/Y2O3 nanocomposite materials to study such effects as particle pushing/engulfment and clustering during repeated processing by synchrotron X-ray tomography. Results demonstrate that microstructural phenomena can be monitored as they evolve during the processing of such materials.
