Figure 2
Two-dimensional (a, b, c) and three-dimensional (d, e, f) representations of an Al-20 wt% Cu binary metal microstructure solidifying using the laser-based furnace. Panels (a, d) show the original unheated microstructure, (b, e) show the sample just below 923 K, and (c, f) show the final structure as-solidified. The Al-rich dendrites are shown in (a, c, d, f) and the eutectic is transparent. The fully liquid structure is shown in (b, e) indicating there are no dendrites at this temperature. |
