Book excerpt: As part of the Metalworking Processes and Equipment Program, information was collected on deformation characteristics of metals and their effect on processing operations. The report presents the information collected from technical engineering reports on Government contracts and from general engineering and metallurgical publications. The objective is to help the nonspecialist in recognizing the implications of scientific findings and in applying them in specific operations. This report contains a series of articles covering the following subjects: Ductile Fracture; Application of High Pressure to the Forming of Brittle Metals; Superplasticity; Lubrication in Metal-Deformation Processes; Swaging; Adiabatic Conditions in Deformation Processing; Residual Stresses produced by Deformation. These subjects are treated in two ways: (1) generalized discussions of common processes point out why specific variables must be modified in order to deform certain types of metals satisfactorily; and (2) data on the more difficult-to-form metals are used to illustrate the principles, limitations, and effects of the processes.

Download or read book The Application of High Pressure in Metal deformation Processing written by F. W. Boulger and published by . This book was released on 1964 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: On October 3, 1963, a symposium was sponsored by the Bureau of Naval Weapons, Metalworking Processes and Equipment Program, on the application of high pressure in metal-deformation processing. Past research has shown that superimposed hydrostatic pressure can significantly increase the ductility at fracture of various materials. These observations have stimulated considerable interest in applying this hydrostatic-pressure effect to metal deformation processing, where it was anticipated that improved ductility and fabricability of brittle materials could be realized. Hydrostatic extrusion and hydrodynamic compressive forging were two such fabrication techniques discussed at the symposium, and preliminary results were found to be encouraging. Another fabrication process that will be investigated in the near future is sheet drawing, where the effect of superimposed pressure improves the ductility to fracture, it was noted that pressure cycling did not improve either the strength or ductility of steels containing various amounts of carbon. In addition to the mechanical-property effects, hydrostatic pressure has been found to affect measurably, numerous metallurgical properties of metals and alloys. (Author).

This book was released on 2012-12-06 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal aim of this text is to encourage the development and application of numerical modelling techniques as an aid to achieving greater efficiency and optimization of metal-forming processes. The contents of this book have therefore been carefully planned to provide both an introduction to the fundamental theory of material deformation simulation, and also a comprehensive survey of the "state-of-the-art" of deformation modelling techniques and their application to specific and industrially relevant processes. To this end, leading international figures in the field of material deformation research have been invited to contribute chapters on subjects on which they are acknowledged experts. The information in this book has been arranged in four parts: Part I deals with plasticity theory, Part II with various numerical modelling techniques, Part III with specific process applications and material phenomena and Part IV with integrated computer systems. The objective of Part I is to establish the underlying theory of material deformation on which the following chapters can build. It begins with a chapter which reviews the basic theories of classical plasticity and describes their analytical representations. The second chapter moves on to look at the theory of deforming materials and shows how these expressions may be used in numerical techniques. The last two chapters of Part I provide a review of isotropic plasticity and anisotropic plasticity.
