| Summary: | The microstructure of an eutectic Al-6,3wt.%Ni alloy solidified under transient conditions were analysed in as-cast condition and after a laser surface remelting process. Considering that the laser treatment reaches a small portion of sample surface and provide higher cooling rates (?) than conventional cast processes, ? had to be calculated with the aid of a computational program. Therefore, microstructure of both as-cast and treated samples were compared. The microstructure of the remelted zone showed cell-like structures, which achieved very refined scale (< 10 ?m). |
