Figure 2
Selected images from the first ever proton radiography sequence of melting (upper images) and solidification (lower images) in a 6 mm thick Al-10 at.% In section.
The In-rich L2 liquid phase appears dark. The monotectic reaction is observed during solidification because macro-scale sedimentation of the denser In-rich L2 liquid phase occurs during melting. The corresponding video (Supplementary Information Video S1) shows the melting and solidification progression.
