What is the critical value of G to avoid constitutional supercooling for the directional solidification of an Al-Cu alloy, containing 3 wt.% copper, at a rate of 0.05 mm/s? For these alloys, k = 0.14, m = -2.6oC/wt% and D = 3x10-5 cm 2 /s. Here G is the thermal gradient into the liquid phase, k is the partition coefficient of the alloy, and D is the diffusivity of solute in the liquid phase.
