Fließpressen ist ein Werkstoff und Zeit sparendes Fertigungsverfahren der Massivumformung. Es spielt für die kostengünstige Herstellung von präzisen, oft einbaufertigen Werkstücken aus Stahl und anderen metallischen Werkstoffen eine zunehmend wichtige Rolle.Das Buch führt systematisch in die Grundlagen und -verfahren des Kalt- und Halbwarmfließpressens ein und stellt die dazugehörigen Werkstoffe, Werkzeuge und Maschinen vor. Wärme- und Oberflächenbehandlung in der Serienproduktion werden ebenso behandelt wie die Verfahrenssimulation und die Berechnung für die Umformgrad- und Presskraftermittlung. Anhand zahlreicher konkreter Praxisbeispiele werden Problemlösungen für bewährte und weniger bekannte Verfahren und Anwendungsfälle vorgestellt.Das Buch wendet sich an Fertigungsingenieure in der Industrie ebenso wie an Wissenschaftler und Studierende in der Fertigungs- und Werkstofftechnik." - Inbunden, Engelska, 2000

After a brief introduction into crystal plasticity,the fun- damentals of crystallographic textures and plastic anisotro- py, a main topic of this book, are outlined. A large chapter is devoted to formability testing both for bulk metal and sheet metal forming. For the first time testing methods for plastic anisotropy of round bars and tubes are included. A profound survey is given of literature about yield criteria for anisotropic materials up to most recent developments and the calculation of forming limits of anisotropic sheet me- tal. Other chapters are concerned with properties of workpieces after metal forming as well as the fundamentals of the theory of plasticity and finite element simulation of metal forming processes. The book is completed by a collection of tables of international standards for formability testing and of flow curves of metals which are most commonly used in metal forming. It is addressed both to university and industrial readers. - Häftad, Engelska, 2010

This book is addressed to both research scientists at universities and technical institutes and to engineers in the metal forming industry. It is based upon the author's experience as head of the Materials Science Department of the In stitut fUr Umformtechnik at the University of Stuttgart. The book deals with materials testing for the special demands of the metal for ming industry. The general methods of materials testing, as far as they are not directly related to metal forming, are not considered in detail since many books are available on this subject. Emphasis is put on the determination of processing properties of metallic materials in metal forming, i. e. the forming behavior. This includes the evaluation of stress-strain curves by tensile, up setting or torsion tests as well as determining the limits of formability. Among these subjects, special emphasis has been laid upon recent developments in the field of compression and torsion testing. The transferability of test results is discussed. Some testing methods for the functional properties of workpieces in the final state after metal forming are described. Finally, methods of testing tool materials for bulk metal forming are treated. Testing methods for surface properties and tribological parameters have not been included. The emphasis is put on the deformation of the specimens. Prob lems related to the testing machines and measuring techniques as well as the use of computers are only considered in very few cases deemed necessary.
