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 feature

An expert exposition of the structural and mechanical properties of light alloys and composites, bridging the gap between scientists and industrial engineers in its consideration of advanced light materials, their structure, properties, technology and application. Includes basic problems of alloy constitution and phase transformations. The aluminium alloys are the main topic of the book, consideration being given to their properties, casting technology, thermomechanical treatment and structure. Attention is also given to the magnesium alloys, particularly those having rare earth metal constituents. Both commercial titanium alloys and intermetallic compounds are discussed, as are metallic composites. The latest engineering techniques are discussed in both theoretical and practical terms.

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.

Magnesium (Mg) alloys are receiving increasing attention due to their abundance, light weight, castability, formability, mechanical properties and corrosion performance. By selecting the appropriate combination of materials, coatings and surface modifications, their corrosion resistance can be greatly enhanced. Corrosion prevention of magnesium alloys is a comprehensive guide to the effective prevention of corrosion in these important light metals. Part one discusses alloying, inhibition and prevention strategies for magnesium alloys as well as corrosion and prevention principles. Part two reviews surface treatment and conversion. Beginning with an overview of surface cleaning and pre-conditioning, the book goes on to discuss the use of surface processing and alloying, laser treatments, chemical conversion and electrochemical anodization to improve the corrosion resistance of magnesium alloys. Coatings are then the focus of part three, including varied plating techniques, cold spray coatings, gel and electroless electrophoresis coatings. Finally, the book concludes in part four with a selection of case studies investigating the application of preventative techniques for both automotive and medical applications. With its distinguished editor and international team of expert contributors, Corrosion prevention of magnesium alloys is a key reference tool for all those working with magnesium and its alloys, including scientists, engineers, metallurgists, aerospace and automotive professionals, and academics interested in this field. Chapters provide an overview of surface cleaning and pre-conditioning Examines processes to improve the corrosion resistance of magnesium alloys, including laser treatments and chemical conversion and electrochemical anodization Discusses cold spray, sol-gel and electrophoretic coatings

The use of magnesium alloys is increasing in a range of applications, and their popularity is growing wherever lightweight materials are needed. This book provides a comprehensive account of the corrosion of magnesium alloys. It covers not only the corrosion performances and mechanisms of Mg alloys in conventional environments, such as sodium chloride solutions, but also looks at their corrosion behaviours in special media, like engine coolants and simulated body fluids. Part one covers fundamentals such as the corrosion electrochemistry, activity and passivity of magnesium and its alloys. Part two then considers the metallurgical effect in relation to the corrosion of magnesium alloys, including the role of micro-structure and earth-rare elements, the corrosion behaviour of magnesium-based bulk metallic glasses, and the corrosion of innovative magnesium alloys. Part three goes on to describe environmental influences on the corrosion of magnesium alloys, such as atmospheric corrosion, stress corrosion cracking, creep and fatigue behaviour, and galvanic corrosion. Finally, part four is concerned with various means of protecting magnesium alloys against corrosion through the use of aluminium electrodeposition, conversion and electrophoretic coatings, and anodisation. With its distinguished editor and team of contributors, this book is an invaluable resource for metallurgists, engineers and designers working with magnesium and its alloys, as well as professionals in the aerospace and automotive industries.

The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.
