This book deals with the fundamental casting technology issues of how metal solidifies within a mould and of when, where and how equiaxed crystals are formed. The author describes how he discovered the phenomenon of crystal separation and established the principle of controlling cast structures, and describes the events leading up to the success of the OCC (Ohno Continuous Casting) Process which enables the continuous production of a single crystal ingot. This book will be of interest to students and researchers as well as to practising engineers.

Metalle mit ihren vielfältigen nützlichen Eigenschaften sind eine der wichtigsten Werkstoffgruppen. Ob elektrische und thermische Leitfähigkeit, Glanz, plastische Verformbarkeit oder auch chemische Beständigkeit – die charakteristischen Eigenschaften von Metallen lassen sich aus ihrem elektronischen Zustand ableiten. Das Buch führt in das interdisziplinäre Fachgebiet der Metallkunde ein und verbindet die Darstellung der physikalischen Struktur und der physiko-chemischen Eigenschaften der Metalle mit ihrer Anwendung als Werkstoffe. Die Autoren beschreiben im ersten, wissenschaftlichen Teil den atomaren und mikroskopischen Aufbau, die thermodynamischen und die grundlegenden physikalischen und mechanischen Eigenschaften der Metalle sowie die Grundlagen der thermisch aktivierten Reaktionen und der Phasenumwandlungen. Die wichtigsten experimentellen Untersuchungsmethoden werden erläutert, wobei die mikroskopischen und Beugungsverfahren einen Schwerpunkt bilden. Im zweiten, technischen Teil werden die Werkstoffgruppen der Metalle und ihre anwendungsbezogenen Eigenschaften behandelt. Dabei wird auf die zugrunde liegenden Legierungen und die Verfahren zur gezielten Einstellung ihrer Eigenschaften eingegangen. Schwerpunkte bei der Darstellung der Werkstoffe sind die Stähle, die teilchengehärteten Legierungen, die Magnetwerkstoffe und die pulvermetallurgisch hergestellten Werkstoffe. Außerdem werden die Oberflächeneigenschaften und die Verfahren zur Oberflächenbehandlung dargestellt. Das Buch wurde für die 7. Auflage gründlich überbearbeitet und aktualisiert. Das Kapitel Mechanische Eigenschaften wurde um das mechanische Verhalten bei hoher Temperatur stark erweitert und die berücksichtigt nun die einschlägigen Normen der Werkstoffprüfung. Das Kapitel Erstarrung wurde um die additive (generative) Fertigung ergänzt, die in den letzten Jahren als computerbasiertes Fertigungsverfahren Einzug in die Produktionstechnik gehalten hat. Als kompaktes Standardwerk eignet sich das Fachbuch sowohl für die berufliche Praxis als auch für das Studium an Universität und Hochschule. Dort richtet es sich an Studierende der Natur- und Ingenieurwissenschaften, insbesondere der Werkstoffwissenschaften.

Stefanescu here attempts to describe solidification theory through the complex mathematical apparatus required for a fundamental treatment of the problem. The mathematics is however restricted to the elements essential to attain a working knowledge in the field. This is in line with the main goal of the book, which is to educate the reader in the fast moving area of computational modeling of solidification of castings. A special effort has been made to introduce the reader to the latest developments in solidification theory including, in this second edition, a new chapter on semi-solid casting.
