This updated edition presents a picture of the majority of solidification phenomena which control the formation of microstructures. Solidification phenomena play an important role in many processes used in a wide range of fields, from production engineering to solid-state physics. Simple models have been developed to attempt to aid understanding of this complex subject. In this text there are a broad range of solidification models to look at, from large tonnage of continously cast products, through superalloy precision casting, to high-purity single crystals. This book is aimed at being useful for students and experienced engineers alike.
