Aluminum sheets produced by continuous casting (CC) provide energy and economic savings of at least 25 and 14 percent, respectively, over sheets made from conventional direct chill (DC) ingot casting and rolling. As a result of the much simpler production route in continuous casting, however, the formability of CC aluminum alloys is often somewhat inferior to that of their DC counterparts. The mechanical properties of CC alloys can be improved by controlling their microstructure through optimal thermomechanical processing. Suitable annealing is an important means to improve the formability of CC aluminum alloy sheets. Recrystallization of deformed grains occurs during annealing, and it changes the crystallographic texture of the aluminum sheet. Laboratory tests in this project showed that this texture change can be detected by either laser-ultrasound resonance spectroscopy or resonance EMAT (electromagnetic acoustic transducer) spectroscopy, and that monitoring this change allows the degree of recrystallization or the ''recrystallized fraction'' in an annealed sheet to be ascertained. Through a plant trial conducted in May 2002, this project further demonstrated that it is feasible to monitor the recrystallized state of a continuous-cast aluminum sheet in-situ on the production line by using a laser-ultrasound sensor. When used in conjunction with inline annealing, inline monitoring of the recrystallized fraction by laser-ultrasound resonance spectroscopy offers the possibility of feed-back control that helps optimize processing parameters (e.g., annealing temperature), detect production anomalies, ensure product quality, and further reduce production costs of continuous-cast aluminum alloys. Crystallographic texture strongly affects the mechanical anisotropy/formability of metallic sheets. Clarification of the quantitative relationship between texture and anisotropy/formability of an aluminum alloy will render monitoring and control of its texture during the sheet production process even more meaningful. The present project included a study to determine how the anisotropic plastic behavior of a continuous-cast AA 5754 aluminum alloy depends on quantifiable texture coefficients. Formulae which show explicitly the effects of texture on the directional dependence of the q-value (a formability parameter) and of the uniaxial flow stress, respectively, were derived. Measurements made on a batch of as-received AA 5754 hot band and its O-temper counterpart corroborate the validity of these formulae. On the other hand, these measurements also indicate that some microstructure(s) other than texture could play a significant role in the plastic anisotropy of the AA 5754 alloy. For the q-value of a set of O-temper samples of this alloy, the additional microstructure that affects plastic anisotropy was shown to be grain shape. A formula that captures both the effects of crystallographic texture and grain shape on the q-value of the O-temper material was derived. A simple quadratic plastic potential that delivers this q-value formula was written down. Verification of the adequacy of this plastic potential, however, requires further investigations.

Direct strip casting is a continuous casting process for producing metallic sheet directly from the molten state that minimises the need for substantial secondary processing. This important book is the first to review the implications of strip casting technology for a range of alloys, including carbon and stainless steel, aluminium, magnesium, titanium, copper and other non-ferrous alloys.The book is divided into six chapters, with the first two describing the physical metallurgy of candidate alloys for direct strip casting and the development of microstructure during solidification. Chapter 3 describes the principles of continuous casting processes and the evolution of direct strip casting. It provides the foundation for the following two chapters which describe process variables and their impact on microstructure and strip quality. The final chapter describes possible techniques in secondary processing and fabrication of the as-cast strip. Two appendices discuss simulation and modelling issues, and the measurement and representation of textures in metal strip.Direct strip casting of metals and alloys is a standard reference on a technology destined to have a profound impact on the manufacturing landscape of the twenty-first century.

The papers published in these peer-reviewed proceedings represent the latest developments in nondestructive characterization of materials and were presented at the Tenth International Symposium on Nondestructive Characterization of Materials held on June 26 - 30, 2000 in Karuizawa, Japan. The symposium was held concurrently with three other symposia and one workshop. This symposium is the tenth in the series that began in 1983 and became an international meeting in 1986. The symposium started with a Plenary Lecture entitled 'Application of Non-contact Ultrasonics to Nondestrctive Characterization of Materials' by Professor R.E. Green, Jr. Various characterization methods were presented at the symposium, including ultrasonics, X-ray, eddy currents, laser, thermal wave, acoustic emission, optical fibers, optics, magnetics and ultrasonic microscope. Thin films and coatings as well as smart materials were also emphasized in this symposium.

These symposium proceedings from the 1998 TMS Fall Meeting examine the relationships between mechanical behavior and microstructural evolution that must be quantified to develop predictive models for hot deformation. Issues addressed include constitutive modeling; process design and modeling; laboratory simulation of large scale hot working processes; the evolution of microstructure; texture, damage, dynamic precipitation, recovery, and recrystallization processes; creep and superplastic deformation; and the ability to predict phenomena such as corrosion and formability after hot deformation.

The possibility of nondestructively characterizing the microstruc ture, morphology or mechanical properties of materials is certainly a fascinating subject. In principle, such techniques can be used at all stages of a material's life - from the early stages of processing, to the end of a structural component's useful life. Interest in the subject thus arises not only from a purely scientific point of view but is also strongly motivated by economic pressures to improve productivity and quality in manufacturing, to insure the reliability and extend the life of existing structures. The present volume represents the edited papers presented at the Second International Symposium on the Nondestructive Characterization of Materials, held in Montreal, Canada, July 21-23, 1986. The Proceedings are divided into eight sections, which reflect the multidisciplinary nature of characterizing materials nondestructively: Polymers and Composites, Ceramics and Powder Metallurgy, Metals, Layered Structures/Adhesive Bonds/Welding, Degradation/Aging, Texture/ Anisotropy, Stress, and New Techniques. Invited papers by R. Hadcock of Grumman Aircraft Systems, R. Cannon of Rutgers University, H. Yada of Nippon Steel and R. Bridenbaugh of Alcoa review respectively the processing of polymer matrix composites, ceramics, steel and aluminum, emphasizing the need for material property sensors to improve process and quality control. Two other invited papers, one by A. Wedgwood of Harwell and the other by P. Holler of the IzFP in Saarbrucken review state of the art techniques to characterize particulate matter and metals respectively.

Texture is a fundamental material characteristic which results from the microstructural evolution that takes place during various processes, including the thermomechanical deformation of materials. Therefore, texture-related phenomena will continue to be of great importance, because of their scientific interest as well as their effect upon industrial applications, in the 21st century. This volume deals with all of the themes which are related to texture phenomena in both conventional and advanced materials, including: ceramics, thin films, polymers, nanocrystalline materials, rocks and composites. The papers cover various texture-related fields: quantitative texture analysis, experimental measurement, modeling, micro-texture analysis, deformation textures, recrystallization and grain growth textures, anisotropic properties, textures in steels, textures in Al and Al-Alloys, textures in thin films, and textures in ceramics, intermetallics and polymers, etc.
