Abstract:

The work comprises a theoretical and experimental study of macrosegregation in solidification of ingots and castings. A general expression is given for macrosegregation, which is viewed as resulting from mass flow into, or out of, local regions of the ingot during solidification. The mass flow considered in detail results from flow of solute rich liquid to feed solidification and thermal contraction.
