This volume discusses the phase composition and structure of iron-containing alloys, the influence of iron on various properties, the harmful effects of iron as an impurity. It considers the effect of iron on the structure and properties of aluminium alloys and defines ways to diminish this effect. The book also explores the use of iron in the development of new alloys and composites. It presents analyses of equilibrium and non-equilibrium phase diagrams and structure of iron-containing alloys to the development of new alloys and composite materials. Iron in Aluminium Alloys: Impurity and Alloying Element is intended for graduate students, engineers and researchers working in materials science and metallurgy.

Magnesium-based alloys containing rare-earth metals are important structural materials, as they combine low density with high-strength properties. This makes them particularly attractive for industry, especially in cases where the low weight of constructions is critical, as in aircraft and space apparatus construction. One of the remarkable features of alloys is the significant difference made by individual rare-earth metals when they are added to magnesium. This second edition of Magnesium Alloys Containing Rare-Earth Metals: Structure and Properties describes the constitution and properties of magnesium-based alloys containing rare-earth metals. It presents the dependence of their characteristics on their atomic number and place in the periodic table and discusses new ideas for rare-earth metals as alloying additives to magnesium. This volume consists mainly of research from Russian scientists but also contains western literature making it a valuable reference tool for students, researchers and professionals in materials science and metallurgy.

This text offers previously elusive information on state-of-the-art Russian metallurgic technology of titanium alloys.

Titanium Alloys: Russian Aircraft and Aerospace Applications addresses all facets of titanium alloys in aerospace and aviation technology, including specific applications, fundamentals, composition, and properties of commercial alloys. It is useful for all students and researchers interested in the investigation and applications of titanium.

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.

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.

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.
