Book Description
The Materials Engineering Division at Frankford Arsenal is involved in an extensive research effort aimed at upgrading the engineering properties of wrought high strength 7000 series aluminum alloys through thermomechanical processing of the ingot material. The development of two new ingot thermomechanical processing techniques, ISML-ITMT and FA-ITMT, is presented. The effects of these techniques on the recrystallization behavior, grain morphology, tensile properties, fracture toughness and stress corrosion resistance of high purity 7075 alloy sheet and plate is presented. The recrystallization of 7075 alloy into a fine grained material was found to be controlled by the distribution of the major alloying elements, Zn, Mg and Cu, as well as by that of the ancillary element, Cr. The results showed that for a given standard temper, i.e., T6, T76 and T73, high purity ITMT processed 7075 alloy has finer grain size, equivalent strength and better ductility, fracture toughness and stress corrosion characteristics than commercial 7075 alloy. The work also showed that high purity ITMT processed 7075 alloy in the FTMT temper (a temper involving a deformation stage between an initial and a final artificial aging stage) has higher strength, ductility and fracture toughness than commercial 7075-T6 alloy.

Book Description
Work is reported on five separate but related research activities on solidification and thermomechanical processing of aluminum ingots. Several of these are completed research activities; others are in progress. They deal with (1) solution treatment of cast Al-4.5% Cu alloy, (2) effect of solution treatment of mechanical properties and fracture behavior of Al-4.5% Cu alloy, (3) effect of thermo-mechanical processing on solution treatment of wrought Al-4.5% Cu alloy, (4) heat flow in unidirectional solidification, and (5) laboratory simulation of the 'negative cone of segregation'.

Book Description
Thermo-Mechanical Processing of Metallic Materials describes the science and technology behind modern thermo-mechanical processing (TMP), including detailed descriptions of successful examples of its application in the industry. This graduate-level introductory resource aims to fill the gap between two scientific approaches and illustrate their successful linkage by the use of suitable modern case studies. The book is divided into three key sections focusing on the basics of metallic materials processing. The first section covers the microstructural science base of the subject, including the microstructure determined mechanical properties of metals. The second section deals with the current mechanical technology of plastic forming of metals. The concluding section demonstrates the interaction of the first two disciplines in a series of case studies of successful current TMP processing and looks ahead to possible new developments in the field. This text is designed for use by graduate students coming into the field, for a graduate course textbook, and for Materials and Mechanical Engineers working in this area in the industry. * Covers both physical metallurgy and metals processing* Links basic science to real everyday applications* Written by four internationally-known experts in the field

Book Description
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.
