The evolution of the microstructure of an AlMg4.7Si8 alloy is investigated by scanning electron microscopy and ex situ synchrotron tomography in as-cast condition and subsequent solution treatments for 1h and 25h at 540°C, respectively. The eutectic Mg2Si phase, which presents a highly interconnecte...
