Differences in density, enthalpy and composition between the liquid and solid are very important for the understanding of solidification processes. A modeling process called scaling is used to understand how material properties and Another solidification curve for the L-section shown in Fig. 34(a) in which a chill has been placed in the B position. 5, A = 1, and B = 2. Note that there is no crossover point in this figure. See also Fig. 34(b) and (c), 35, and 36. geometry can be analyzed in the context of the hierarchal time and length scales associated with the effects of transport phenomena on important features of cast microstructures (Ref 7).

25. 5. Compare with Fig. 29. Fig. 31 In a simple plate having a constant thickness T, a set of solidification fronts will move from each of its surfaces until they meet at its centerline. However, as these fronts move together, their dendritic character begins to cause a blockage of the metal flow from a feeding path, which will result in some degree of shrinkage. This phenomenon has been quantified, and it has been determined that the ability of a riser to feed through a plate is very limited (Ref 6).
