A multitude of steel components undergo heat treatment for property alteration. This practice-oriented book provides a vivid overview of the various influencing factors throughout the lifecycle of such products, from design to deployment. Using numerous examples, it illustrates potential sources of errors associated with heat treatment and how to avoid them. Drawing on decades of experience in the field of technical failure analysis, the author provides valuable guidance for both students and practitioners. Content Area of Influence: Design and Engineering Area of Influence: Material Purchasing Area of Influence: Materials Area of Influence: Manufactoring before Heat Treatment Area of Influence: Heat Treatment Area of Influence: Manufactoring after Heat Treatment Area of Influence: Operating Conditions Target Groups Engineering students Practitioners in development, manufacturing, and deployment Author Professor Dr.-Ing. Peter Sommer is the managing partner of Dr. Sommer Werkstofftechnik and teaches as a lecturer at Hochschule Rhein-Waal in the fields of material testing and failure analysis. He has also been teaching the lecture "Der Werkstoff Stahl" at the University of Duisburg-Essen for many years. The translation was done with the help of artificial intelligence. A subsequent human revision was done primarily in terms of content.
