Materials Processing During Casting

This text covers most aspects of casting. It deals with the principles behind modern casting with applications incorporated for both ferrous and non–ferrous metals. The text consists of 11 chapters: Chapters 1–2 presents a short introductory survey methods and equipment.Chapters 3–6 describe the theoretical basis behind modern casting processes in foundries and cost houses.Chapters 7–11 have a more practical approach to the casting of various metals. The principles derived in the earlier chapters are applied to teach the reader how various problems can be designed in an optimal way, according to the present knowledge of casting science. Due to the importance of steel and iron–based alloys a good deal of the content is devoted to these alloys but the principles and phenomena are general.
Most chapters contain several solved examples and at the end of chapters 3–11 aa selection of exercises is given. The answers to all of the exercises are listed at the end of the book.
An accompanying ′Guide to exercises′ provides complete solutions to all of the exercises, step by step. The solutions in the Guide are designed to encourage the students to work on their own, i.e. the idea is help to self–help to achieve increased understanding of the topic. The Guide can be downloaded in PDF format from www.wiley.com.
This extensive book offer materials for several courses on different aspects of the subject with the option of varying the level of the courses. It is appropriate for undergraduate as well as masters students in materials technology, as well as for students in mechanical engineering with some knowledge of materials processing. This text can be used by PhD students and researcher in material science who are working with problems connected to casting processing.
