Numerical Models of Solidification and their Application in Metal and Ceramic Technology
Solidification (crystallization) phenomena play a major role in such diverse operations
as casting, crystal growth, and welding. Solidification proceeds at various rates,
which are sometimes far from equilibrium. Thus, the micro-structure obtained is
generally not homogeneous and gives rise to variations in composition with
position at both small and large scales, which is known as segregation.
Solute segregation is important because it leads to non-equilibrium phases, cracks,
and other problems, which lower the mechanical properties of the final product.
Segregation is classified, according to its scale, as macro-segregation or micro-segregation...
