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.

Book excerpt: As part of the Metalworking Process and Equipment Program, a survey was conducted to collect and summarize information on deformation characteristics of metals and their effect on processing operations. This report presents information obtained from reports on Governmentsponsored work and from articles in technical publications. The report covers eight subjects: extrusion, forging, rolling, thermal mechanical variables affecting the properties of refractory metals and alloys, development of preferred orientations, anisotropy of strength and ductility, high-strain-rate deformation, and strain aging. In order to be useful to engineering students and production engineers the topics are treated in two ways. Generalized discussions of common processes point out why specific variables must be modified in order to deform certain types of metals satisfactorily. When practical, data on the more-difficultto-form metals are used to illustrate the principles, limitations, and effects of the processes. The objective is to help the non-specialist recognize the implications of specific findings and to apply them to specific operations. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Manufacturing, reduced to its simplest form, involves the sequencing of product forms through a number of different processes. Each individual step, known as an unit manufacturing process, can be viewed as the fundamental building block of a nation's manufacturing capability. A committee of the National Research Council has prepared a report to help define national priorities for research in unit processes. It contains an organizing framework for unit process families, criteria for determining the criticality of a process or manufacturing technology, examples of research opportunities, and a prioritized list of enabling technologies that can lead to the manufacture of products of superior quality at competitive costs. The study was performed under the sponsorship of the National Science Foundation and the Defense Department's Manufacturing Technology Program.

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).
