Metal Deformation Processing

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).

Advances in Deformation Processing

The Army Materials and Mechanics Research Center has con ducted the Sagamore Army Materials Research Conference in coop eration with the Materials Science Group of the Department of Chemical Engineering and Materials Science of Syracuse University since 1954. The purpose of the conference has been to gather to gether scientists and engineers from academic institutions, in dustry and government who are uniquely qualified to explore in depth a subject of importance to the Army, the Department of Defense and the scientific community. This volume, Advances in Deformation Processing, addresses the areas of Analytical Advances, Workability, Processing to Optimize Properties, Advanced Applications - Materials, and Advanced Applications - Processes. The dedicated assistance of Mr. Joseph Bernier of the Army Materials and Mechanics Research Center throughout the stages of the conference planning and finally the publication of the Sagamore Conference Proceedings is deeply appreciated. The support of Helen Brown DeMascio of Syracuse University in p- paring the final manuscript is acknowledged. The continued active interest and support of these conferences by Dr. A. E. Gorum, Director of the Army Materials and Mechanics Research Center, is appreciated. Syracuse University Syracuse, New York The Editors vii Contents SESSION I INTRODUCTION A. E.
