... and unfurling on mechanical properties of the solidified cast metal. It provides a discussion on the mechanisms of unfurling to determine the casting properties of the metals. These include gas precipitation, shrinkage, linear contraction, dendrite pushing, and nucleation and growth of intermetallics...

... at the location of the last liquid to solidify. Figure 3 shows the formation of a shrinkage cavity in a pure metal solidifying in a mold where all heat is removed through the mold. If the final casting is to have the same volume as the liquid, a reservoir of molten metal must be placed on the casting to feed...
