In situ study of Ni-20Cr wire in molten 50:50 mol% KCl:MgCl2 at 800°C. Before heating, the pristine sample (a) is homogeneous and free of major defects. After only 16 min (b) at temperature, significant corrosion has taken place. After 33 min (c) corrosion has further progressed, resulting in a bi-continuous pore formation. After 185 min (d) surface coarsening drives the formation of elongated and smooth channels.
