Processing And Characterization Of Magnesium Based Materials

Due to their lightweight and high specific strength, Mg-based alloys are considered as substitutes to their heavier counterparts in applications in which corrosion is non-relevant and weight saving is of importance. Furthermore, due to the biocompatibility of Mg, some alloys with controlled corrosion rates are used as degradable implant materials in the medical sector. The typical processing route of Mg parts incorporates a casting step and, subsequently, a thermo–mechanical treatment. In order to achieve the desired macroscopic properties and thus fulfill the service requirements, thorough knowledge of the relationship between the microstructure, the processing steps, and the resulting property profile is necessary. This Special Issue covers in situ and ex situ experimental and computational investigations of the behavior under thermo–mechanical load of Mg-based alloys utilizing modern characterization and simulation techniques. The papers cover investigations on the effect of rare earth additions on the mechanical properties of different Mg alloys, including the effect of long-period stacking-ordered (LPSO) structures, and the experimental and computational investigation of the effect of different processing routes.

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.

In the automotive and aerospace industries, the need for strong yet light materials has given rise to extensive research into aluminum and magnesium alloys and formable titanium alloys. All of these are categorized as light weight materials. The distinguishing feature of light weight materials is that they are low density, but they have a wide range of properties and, as a result, a wide range of applications. This book provides researchers and students with an overview of the recent advancements in light weight material processing, manufacturing and characterization. It contains chapters by eminent researchers on topics associated with light weight materials, including on the current buzzword “composite materials”. First, this book describes the current status of light weight materials. Then, it studies applications of these materials, given that, as the densities vary, so do the applications, ranging from automobiles and aviation to bio-mechatronics. This book will therefore serve as an excellent guide to this field.

"This book of contributed chapters will provide the resources necessary for processing, characterization and manufacturing using lightweight materials across the globe, offering recent advances in the field of light weight material usage and its recent developments"--

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 matrix composites, as light and strong materials, are very attractive for different industrial fields. In the present work, nano and micro-composites reinforced with ceramic particle (1 wt.%) were fabricated with ultrasonic-assisted process. Microstructural characterization was investigated by Transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The investigation revealed Complex phenomena and different behaviors between particles in terms of particle pushing, particle agglomeration, chemical reactions reaction and in situ formation of new particles in the melt. The EL21+AlN composite exhibits the best mechanical properties which were correlated to its microstructure. A three bodies model was applies to our composites systems, this model give an estimation of the possibility of nanoparticle capture through calculation of the Hamaker constant of each system. This model allowed also the correlation between the good mechanical properties of the EL21+AlN composite.

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.
