Lightweight alloys have become of great importance in engineering for construction of transportation equipment. At present, the metals that serve as the base of the principal light alloys are aluminum and magnesium. One of the most important lightweight alloys are the aluminum alloys in use for several applications (structural components wrought aluminum alloys, parts and plates). However, some casting parts that have low cost of production play important role in aircraft parts. Magnesium and its alloys are among the lightest of all metals and the sixth most abundant metal on earth. Magnesium is ductile and the most machinable of all metals. Many of these light weight alloys have appropriately high strength to warrant their use for structural purposes, and as a result of their use, the total weight of transportation equipment has been considerably decreased.

Light Alloys: From Traditional Alloys to Nanocrystals, Fifth Edition, covers the materials science, properties, manufacturing processes, and applications of key engineering metals in a single accessible volume. As use of these metals is now more widespread than ever, with routine use in motor vehicles and aircraft, this book includes materials characteristics and applications, heat treatment properties, fabrication, microstructure/property relationships, new applications, and processes. Provides a definitive, single volume overview on the light alloys Presents new material on the processing, characteristics, and applications of these essential metals Covers the latest applications and processes in the auto and aero industries

Thoroughly revised and updated, this third edition of lan Polmear’s Light Alloys provides the definitive overview of the metallurgy of aluminum, magnesium and titanium alloys. The emphasis remains on manufacturing processes and application areas, in which there have been significant advances in recent years. The extraction of each metal is considered briefly, followed by its casting characteristics and alloying behavior. Sections on heat treatment properties, fabrication and major applications have been expanded to give more comprehensive coverage of the subjects. Particular attention has been paid to microstructure/property relationships as well as to the role of the individual alloying elements, and new materials and novel processes are reviewed in an additional chapter. This succinct and informative introduction to the physical metallurgy of the light alloys will be essential reading for advanced undergraduates in metallurgy, materials science, manufacturing and mechanical engineering. It will also prove invaluable to metallu## gists and engineers in industry seeking to expand on their knowledge.

Aluminium, magnesium and titanium are alloys of special interest for engineering applications in a wide range of sectors such as aeronautics, automotive and medical. Their low density, along with sufficient mechanical properties, makes them especially adequate for sectors such as transportation allowing diminishing weight less fuel consumption and emissions to the atmosphere. Nowadays, machining is still one the most important manufacturing processes, not only for metal parts, but also for specially designed hybrid parts for more demanding new applications. A wide range of valuable research has been done on the machining of conventional engineering materials. However, when dealing with light alloys and hybrid materials containing them, they need to face new challenges. Particularly, it is important to analyse the suitability of the machining of these alloys in the current context of Industry 4.0, focusing on the development of cost-effective and sustainable processes. This book is a comprehensive source on the machining of light alloys, presenting a collection of both experimental and review studies. The work is arranged in eight chapters, presented by a group of international scholars, which analyse the main problems related to the machining of these alloys from different perspectives. Key Features A comprehensive state-of-the-art reference source on machining of light alloys Provides research on conventional and non-conventional machining process Offers current research topics on sustainable machining Presents research on the machining of hybrid materials using light alloys Includes applications for Industry 4.0 environments Machining of Light Alloys: Aluminum, Titanium, and Magnesium The aim of the book is to serve as a tool for helping researchers and practitioners to face machining challenges and facilitating the development of new industrial applications for light alloys.

Armor plays a significant role in the protection of warriors. During the course of history, the introduction of new materials and improvements in the materials already used to construct armor has led to better protection and a reduction in the weight of the armor. But even with such advances in materials, the weight of the armor required to manage threats of ever-increasing destructive capability presents a huge challenge. Opportunities in Protection Materials Science and Technology for Future Army Applications explores the current theoretical and experimental understanding of the key issues surrounding protection materials, identifies the major challenges and technical gaps for developing the future generation of lightweight protection materials, and recommends a path forward for their development. It examines multiscale shockwave energy transfer mechanisms and experimental approaches for their characterization over short timescales, as well as multiscale modeling techniques to predict mechanisms for dissipating energy. The report also considers exemplary threats and design philosophy for the three key applications of armor systems: (1) personnel protection, including body armor and helmets, (2) vehicle armor, and (3) transparent armor. Opportunities in Protection Materials Science and Technology for Future Army Applications recommends that the Department of Defense (DoD) establish a defense initiative for protection materials by design (PMD), with associated funding lines for basic and applied research. The PMD initiative should include a combination of computational, experimental, and materials testing, characterization, and processing research conducted by government, industry, and academia.
