Magnesium Alloys Processing Potential And Applications

This book focuses on the processing, potential, and new applications of magnesium alloy systems. To date, the automotive industry uses the unique properties of magnesium alloys on the largest scale. However, scientists propose the use of magnesium and its alloys in many new areas and industries. As such, this book describes and reports on the progress of research on magnesium alloys, for example, in the oil and gas, implantology, and thermoelectric industries. Due to their availability and relatively high mechanical properties combined with low density, magnesium alloys are a dynamically developed group of light metal alloys. Both scientists and industrial centers are involved in expanding the application possibilities of magnesium-based alloys. New applications proposed in this book are examined in relation to technology, functional properties, and potential of the tested materials. The book also examines related challenges of magnesium-based alloys, including implementation problems, encountered barriers and problems to be solved in the scope of the proposed application were described also.

Magnesium is the lightest of all the metals and the sixth most abundant on Earth. Magnesium is ductile and the most machinable of all the metals. Magnesium alloy developments have traditionally been driven by requirements for lightweight materials to operate under increasingly demanding conditions (magnesium alloy castings, wrought products, powder metallurgy components, office equipment, nuclear applications, flares, sacrificial anodes for the protection of other metals, flash photography and tools). The biggest potential market for magnesium alloys is in the automotive industry. In recent years new magnesium alloys have demonstrated a superior corrosion resistance for aerospace and specialty applications. Considering the information above, special issues on magnesium alloys are exposed in this book: casting technology; surface modification of some special Mg alloys; protective carbon coatings on magnesium alloys; fatigue cracking behaviors of cast magnesium alloys and also, magnesium alloys biocompatibility as degradable implant materials.

Magnesium alloys have been attractive to designers due to their low density (two thirds that of aluminium), the sixth most abundant on earth, is ductile and the most machinable of all the metals. This has been a major factor in the widespread use of magnesium alloy castings and wrought products, powder metallurgy components, sacrificial anodes for the protection of other metals, tools. The present book, "New Features on Magnesium Alloys", gives us an overview in some special areas of magnesium alloys concerning technological applications and eco-friendly requirements. Each chapter brings us a new facet relating to the magnesium alloy application: magnesium alloys quasicrystals used to magnesium alloys reinforcement; rare earth metals as alloying components in magnesium implants for orthopaedic applications; magnesium alloys surface treatment by applying physical vapor deposition processes; casting magnesium alloys subjected to laser treatment; ductility enhancement on special magnesium alloys; welding and joining processing of magnesium alloys; transport application of magnesium and its alloys.

The need for light-weight materials, especially in the automobile industry, created renewed interest in innovative applications of magnesium materials. This demand has resulted in increased research and development activity in companies and research institutes in order to achieve an improved property profile and better choice of alloy systems. Here, development trends and application potential in different fields like the automotive industry and communication technology are discussed in an interdisciplinary framework.

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.
