Analyzes the extensive experimental and theoretical results on the phase composition, structure and properties of aluminium alloys containing scandium. The text studies the effects of scadium on these properties from a physico-chemical viewpoint. The authors present binary, ternary and more complex phase diagrams for these alloys and consider in detail recrystallization, superplastic behaviour and decomposition of supersaturated solid solutions and the effects of solidification conditions on phase equilibria. The microstructure stability for aluminium alloys containing scandium is estimated, based on a quantitative analysis of the alloys structure and properties. The realtion between the structure and properties of alloys with differing phase compositions, and tha acting hardening mechanisms are discussed. The authors also give some practical recommendations for alloying aluminium alloys with scandium. The experimental results presented in this book have provided a basis for the development of commercial aluminium alloys for a wide range of industrial applications.

Spawned by growing interest in ultrasonic technology and new developments in ultrasonic melt processing, the Second Edition of Ultrasonic Treatment of Light Alloy Melts discusses use of ultrasonic melt treatment in direct-chill casting, shape casting, rapid solidification, zone refining, and more, exploring the effects of power ultrasound on melt degassing, filtration, and refinement in aluminum and magnesium alloys. The fully revised and restructured Second Edition: Contains new, in-depth coverage of composite and nanocomposite materials Provides a historical review of the last century of ultrasonic applications to metallurgy Emphasizes the fundamentals, mechanisms, and applications of ultrasonic melt processing in different light-metal technologies Features new chapters on ultrasonic grain refinement, refinement of primary solid phases, and semi-solid processing of billets with nondendritic structure Includes significant updates reflecting results obtained over the past two decades on different scales, from laboratory to full-scale industrial implementations Complete with many new figures and examples, Ultrasonic Treatment of Light Alloy Melts, Second Edition delivers a comprehensive treatise on ultrasonic melt processing and cavitation, presenting essential guidelines for practical use and further development of the technology.

Pulling together information previously scattered throughout numerous research articles into one detailed resource, Physical Metallurgy of Direct Chill Casting of Aluminum Alloys connects the fundamentals of structure formation during solidification with the practically observed structure and defect patterns in billets and ingots. The author examines the formation of a structure, properties, and defects in the as-cast material in tight correlation to the physical phenomena involved in the solidification and the process parameters.

The book draws on the author's advanced research to provide a unique application of physical metallurgy to direct chill (DC) casting technology. He examines structure and defect formation- including macrosegregation and hot tearing. Each technology-centered chapter provides historical background before reviewing current developments. The author supports his conclusions with computer simulation results that have been correlated with highly progressive experimental data. He presents a logical system of structure and defect formation based on the specific features of the DC casting process. He also demonstrates that the seemingly controversial results reported in literature are, in fact, caused by the different ratio of the same mechanisms.

Compiling recent results and data, the book discusses the fundamentals of solidification together with metallurgical and technological aspects of DC casting. It gives new insight and perspective into DC casting research.

As laboratories replace heavy hydraulic presses and bulky high-pressure chambers with miniature diamond anvils, traditional heaters with laser heating, and continue to improve methods of shock compression, there has been considerable new data obtained from the high-pressure, high-temperature modification of pure elements. The dense metallic modification of elements shows the potential for achieving superconductivity akin to theoretical predictions. Phase Transformations of Elements Under High Pressure contains the latest theoretical and experimental information on nearly 100 elements, including first-and second-phase transitions, melting lines, crystal structures of stable and metastable phases, stability of polymorphic modifications, and other useful properties and data. It emphasizes features such as changes in the liquid state, amorphization, and metallization, and provides temperature-pressure diagrams for every element. The book also describes the transitions of polymeric forms of fullerene, crystal modifications of elements stable under high pressures, and provides data that confirms their superconducting and magnetic properties. This handbook will be a lasting reference for scientists in a broad range of disciplines, including solid-state physics, chemistry, crystallography, mineralogy, and materials science.

This book explores the application of external physical fields to the solidification processing of metallic alloys. Leading academics from around the world present comprehensive and critical reviews on state-of-the-art research and discuss possible future directions. Major physical fields, including electromagnetic, electric, acoustic, and thermal, are considered. In addition, the most advanced synchrotron X-ray based real-time and in-situ studies and numerical modeling methodologies are reviewed and discussed, with a special emphasis on their applications to the solidification processes. Throughout, all chapters are illustrated with both historical and very recent research cases, including typical examples of in-situ studies, modeling, and simulation. This book contains essential knowledge and information suitable for a wide audience, from undergraduate and postgraduate students to academics, practicing researchers, and engineers in materials, metallurgy, and manufacturing.
