Abstract
The topology of coarsened microstructures is investigated on a directionally solidified Al-15wt.pct. Cu sample for five coarsening times. Topological characterization included the measurement of the genus of the majority phase and the number of liquid particles as a function of coarsening time. The genus decreased with coarsening time due to (1) the microstructure becoming less complex through the coarsening process and (2) the increased number of liquid particles due to Rayleigh instability of the liquid-filled cylinders found in the microstructure.
