Abstract
A lot of work on the eutectic structure in cast aluminium alloys has been carried out. However, no pearlite-like eutectic structure has been reported so far. This kind of structure was found when observing the laser-melted zone of the material by TEM. The material used in the present study was aluminium silicon eutectic alloy ZL 108. Its chemical composition in wt% is 12Si, 1.00Fe, 1.23Cu, 0.5Mn, 0.93Mg and 0.1 rare earth (RE). The RE contains 10wt% Ce
