Interface position
z0(t) vs. t of
a SCN/C152 sample (V = 0.549 μm/s,
G = 20.2 K/cm, C∞ =
0.30 wt%). Comparisons with WL calculation (solid line), WL analytic
approximation (dotted line), and sample movement (dashed line) are
shown. (Inset) Long-time behavior, where the WL
prediction breaks down due to solute trapping.
