Teaching and exercise book on materials science and materials testing for training, education, study, and practice. This textbook describes the structure and properties of the most important metallic and non-metallic materials. The main chapters cover steels, cast iron materials, important non-ferrous metals and their alloys, plastics, ceramic materials, and composite materials. The book is characterized by its strong practical relevance, as it addresses the complex interactions between material properties and manufacturing processes. A separate chapter provides information on materials testing in the context of materials development and quality assurance. Additionally, the reader receives an up-to-date and visually clear overview of European and international materials standardization, supported by numerous examples. New in the 7th edition: The entire textbook has been thoroughly revised, expanded to include current topics, and aligned with the latest developments in European and international standards.
