As part of this thermal management, foundry designers have traditionally incorporated a range of molding techniques to promote directional solidification. Coupled with solidification modeling tools, casting designs have become aggressive, requiring process control to be equally important factors in casting yield and scrap.

The temperature of this inflection point is identical with the temperature of the rapid decrease of plasticity to 0, indicating the start of melting at the grain boundaries for the polycrystalline metal and interdendritic zones for the alloy with directional solidification. Thus, the zero plasticity temperature ([T.sub.z.pl.]) characterises the process of the start of melting of the cast metal at high temperatures.
