Book Description
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.

Book Description
Magnesium and magnesium alloys provide unique properties for engineering applications. Magnesium alloys are popular as a structural material because of their combination of light weight and strength. They are desirable for portable tools, appliances, electronic devices, airplanes, space vehicles, and land transportation. This book is written for engineers, scientists, teachers, and students engaged in the design process of material selection and material elimination. While focused on mechanical properties for structural design, the physical properties that are germane to corrosion behavior and electrical applications are represented. Two-thirds of the book is devoted to datasheets for individual alloys which provide a handy quick reference to specific properties and performance. The remainder of the book addresses topics common to all magnesium alloys such as the alloy designation system and product forms. Casting alloys and wrought alloys are compared. The alloy performance at elevated temperature is presented, as are fatigue properties. Finally, a summary of the corrosion behavior of selected alloys is discussed along with how these corrosion mechanisms can be applied for beneficial results.

Book Description
Magnesium alloys with their unique physical and chemical properties are important candidates for many modern engineering applications. Their density, being the lowest of all structural metals, makes them the primary choice in global attempts aimed at reducing the weight of transportation vehicles. However, magnesium also creates challenges at certain stages of raw alloy melting, fabrication of net-shape components and their service. The first one is caused by very high affinity of magnesium to oxygen, which requires protective atmospheres increasing manufacturing cost and heavily contributing to greenhouse gas emissions. The second challenge relates to very high corrosivity of liquid magnesium towards materials it contacts. This imposes restrictions on the selection of materials used to contain, transfer or process molten magnesium during manufacturing operations. A mixture of unique benefits and serious challenges of magnesium alloys in solid and liquid states described here makes the book very useful for a broad audience of scientists and engineers from academia and industry.

Book Description
A look at the current and future uses of magnesium-based products and their role in the world's environmental and technological revolution The lightest of all structural metals, having one-fourth the density of steel and two-thirds that of aluminum, magnesium has already been adopted as an alternative construction material in applications as far ranging as automotive and sports equipment, electronics, and space technology. In a world concerned with minimizing the environmental impact of products, the choice of light-weight, energy-saving, and high-performance materials, like magnesium, would seem a small, significant step towards improving life on this planet. Magnesium, Magnesium Alloys, and Magnesium Composites introduces the science and current applications of this important metal, shedding light on the magnesium-based composites developed over the last fifteen years. Chapters include in-depth discussion of: The characteristics of pure magnesium—including atomic properties and crystal structure as well as physical, electrical, and mechanical properties Magnesium alloys—and the effects of the alloying elements, such as aluminum, lithium, copper, nickel, and silicon The properties of magnesium-based composites—and the effects of different types (metallic, ceramic, interconnected, and intermetallic) of reinforcements of varying length (from micron scale to nanometric length) Corrosion aspects of magnesium-based materials Magnesium-based products in medicine, sports equipment, and the automotive, aerospace, and electronics industries Bringing together, for the first time, the science, properties, and technologies relating to the current and future uses of magnesium, this important reference also offers readers a glimpse of a not-too-distant world in which environmental safety and sound engineering are a reality.

Book Description
Despite their tremendous potential, Mg and its alloys are not yet used in biomedical applications. This book aims to provide scientific insights into the challenges of the materials, and give an overview of the research regarding their mechanical properties, corrosion behaviour and biological performances. The authors intend to put the reader into the position to accurate discern the proper Mg-based material for his/her applications and to choose the proper improvement strategy to his/her cause. To this aim, the manuscript is structured as follow: in Section 2, the main challenges hampering the use of magnesium in biomedical applications and the common improvement strategies are listed. In Section 3, the most investigated Mg alloys are reported in separate sub-sections, detailing their mechanical properties, corrosion behaviour and biotoxicity. High-pure and ultra-high-pure Mg, Al-based Mg alloys, Zn-based Mg alloys, Ca-based alloys and RE-based Mg alloys have been considered. In Section 4, the alloys’ performances with respect to the challenges is summarized providing the reader with useful information and suggestions on the potentially most suited choice. Finally, in Section 5, an outlook portraying the authors’ opinion of the future development of the field will be provided. This book will allow biomedical engineers, surface scientists, material scientists, implant manufacturers and companies working on implant approval an overview of the state-of-the-art technologies adopted so far to overcome the drawbacks of Mg for biomedical applications. Particular emphasis is put on explaining the link between mechanical, corrosion and biocompatible properties of Mg and its alloys as well as their pros and cons. In doing so, the authors intend to put the reader into the position to accurate discern the proper Mg-based material for his/her applications and to choose the proper improvement strategy to his/her cause.
