The coarsening of solid Sn-rich particles in Pb-Sn liquid in a microgravity environment is examined. Volume fractions from 0.1 to 0.8 are analyzed. The low volume fraction samples allow for a direct comparison to coarsening theories with out any adjustable parameters. It was found that the system was not coarsening in a self similar manner, but rather evolved toward the steady-state conditions predicted by theory. The steady-state regime was not reached, even though for volume fractions 0.1 and 0.2, there was a increase of the average particle size by a factor of nearly 3. Also the spatial correlations for volume fractions ≤ 0.3 evolved in time. The evolution of these volume fractions agree with the predictions of a theory describing transient coarsening. We show that the rate at which the coarsening process approaches steady-state decreases as the volume fraction increases.
