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.

Within sections on densification, chemical methods, and physical methods, they discuss such topics as fundamentals and practice of sintering, processing and applications of sol-gel glass, the chemical vapor deposition of structural ceramics and composites, directional solidification
, and processing ceramics by plasma spraying.
LDK Solar Co Ltd (LDK Solar) (NYSE:LDK), a manufacturer of multicrystalline solar wafers and PV products, announced on Monday that its patent 'Directional Solidification
Furnace with Recharging Apparatus for Multicrystalline Silicon Ingot Growth' has won the Excellence Award of the 12th China Patent Award, which is reportedly considered the highest award in the patent field in China.
Understanding of the distinction between conventional casting and directional solidification
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.
