  • 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.

  • This book critically summarizes the effects of various suitable alloying elements and particulate reinforcements on mechanical and degradation properties of pure Mg and Mg alloys targeting biomedical applications.  The suitability of alloying elements and particulate reinforcements are discussed based on their levels of toxic effects on human body.  First attempt is made to study and discuss on the various available synthesizing techniques for fabrication of both impermeable and porous Mg materials.  Further, more emphasis on development of new magnesium matrix nanocomposites (MMNC) is made owing to the similarities between natural bone and MMNCs as bio-"nanocomposite".  The information on synthesis, toxicity of alloying elements and reinforcements and their effects on mechanical and degradation properties of pure Mg will enable the researchers to effectively design Mg alloys and composites targeting biomedical applications.

  • The primary focus of this book, accordingly, is to provide insight into the fundamentals, applications, manufacturing aspects and properties (mechanical, thermal, electrical etc.) of metal foams. Their potential applications in various small- as well as large-scale industries are highlighted. The present book also focuses on aspects of designing simple structures by taking into account loading conditions under tensile, compressive or torsional stress for metals and their foams. In view of theoretical analysis, clear explanation is provided as how metal foams can exhibit better structural properties when compared to their parent metal. It is hoped that the present book, in view of significant application potential of metal foams in near future, will be extremely useful to students and academicians in tertiary institutes and researchers working in research labs who are attempting to find lightweight solutions.

  • This reference book provides a detailed discussion on the protection challenges that arise due to technological improvements in transmission and distribution systems to supply increasing power demand. The primary focus of this book is transmission line protection with FACTS devices connected to the line and islanding detection in an active distribution system i.e., microgrids.

    First, a literature review on the protection of transmission lines in the presence of switching devices is presented. The following chapters then present commonly proposed modifications required in the power system to meet increasing power demands, commonly used existing protection schemes and their limitations in the presence of switching devices, and solutions to these limitations in protection schemes. Results from fault simulations using PSCAD/EMTDC and MATLAB are also included.

    This book will be valuable to graduate students and practicing engineers alike for dealing with protection issues in transmission and distribution systems incorporating FACTS devices.Provides thorough knowledge of trends in transmission networks for the enhancement of power flow, control and protectionPresents an analysis of requirements of microgrids in the future Highlights challenges in the protection of active distribution systems or microgrids against islanding in the presence of distributed generation
