Subvolume 2C of Group VIII deals with the forming data of metals. The content is subdivided into two parts with the present part 1 covering ferrous alloys, i.e. about 170 steel grades, in a compact, database-oriented form. The knowledge of the deformation behaviour of materials is of vital importance in scientific research and in technical applications. The increasing use of numerical simulation in research and practice describes the real processes the better the more precise the response of the material, the processes at the interface between the material and the tools or technical facilities are characterized. This behaviour is affected by process and material related parameters and is represented by physical and mechanical properties, plasticity curves and flow curves in the different states of the respective material. In this volume these properties are given for every single steel along with its detailed composition and useful international standard notations. An extensive introduction presents the fundamental terms and concepts of steel forming with special attention to numerical simulation process related properties. The variety of steel grades discussed emphasizes the relevance of the book as a compendium for scientists, researchers and engineers in metallurgical plants.
