Erosive wear is characterized by successive loss of material from the surface due to the continuous impact of solid particles. This type of wear affects numerous industries, such as power generation, mining, and the pneumatic transportation of solids. The worst case scenario normally occurs where there is a combination of both erosion and oxidation, especially at high temperatures. In order to minimize damage caused by erosive wear, many authors propose the use of better bulk materials or surface coatings, and generally cermets are suggested. Various researchers have conducted experiments to study the wear mechanisms occurring in this kind of materials, but most of these experiments do not lead to similar results; in fact, there is no accordance among the authors, and moreover, some wear variables are ignored. In this book, studies undertaken in this field by several investigators have been discussed extensively. At the end of it, table reviews are suggested to summarize the most important mechanisms of the erosive wear in bulk and coating cermets.
This book discusses the current biomaterials used for dental applications and the basic sciences underpinning their application. The most critical structures in the oral cavity are the teeth, which play a central role in speaking, biting, chewing, tasting and swallowing. Teeth consist of three types of tissue: the cementum, enamel and dentin, with bone and gingival tissue serving as supporting structures. Caries, tooth wear, trauma and mechanical defects can lead to severe facial conditions; however, correcting these defects remains a challenge for scientists and dentists. Presenting insights form a broad range of disciplines, including materials science, biology, physiology and clinical science, this book provides a timely review of the principles, processing and application of dental materials.

Also, the principles of nanoparticle formation are described. It is a useful read to all those interested in low cost synthesis of nanostructured powders and coatings.
Fatigue has long been recognized as a mechanism that can provoke catastrophic material failure in structural applications and researchers are now turning to the development of prediction tools in order to reduce the cost of determining design criteria for any new material. Fatigue of Fiber-reinforced Composites explains these highly scientific subjects in a simple yet thorough way. Fatigue behavior of fiber-reinforced composite materials and structural components is described through the presentation of numerous experimental results. Many examples help the reader to visualize the failure modes of laminated composite materials and structural adhesively bonded joints. Theoretical models, based on these experimental data, are demonstrated and their capacity for fatigue life modeling and prediction is thoroughly assessed. Fatigue of Fiber-reinforced Composites gives the reader the opportunity to learn about methods for modeling the fatigue behavior of fiber-reinforced composites, about statistical analysis of experimental data, and about theories for life prediction under loading patterns that produce multiaxial fatigue stress states. The authors combine these theories to establish a complete design process that is able to predict fatigue life of fiber-reinforced composites under multiaxial, variable amplitude stress states. A classic design methodology is presented for demonstration and theoretical predictions are compared to experimental data from typical material systems used in the wind turbine rotor blade industry. Fatigue of Fiber-reinforced Composites also presents novel computational methods for modeling fatigue behavior of composite materials, such as artificial neural networks and genetic programming, as a promising alternative to the conventional methods. It is an ideal source of information for researchers and graduate students in mechanical engineering, civil engineering and materials science.

This book explores the interconnections and differentiations between artisanal workshops and alchemical laboratories and between the arts and alchemy from Antiquity to the eighteenth century. In particular, it scrutinizes epistemic exchanges between producers of the arts and alchemists. In the fifteenth and sixteenth centuries the term "laboratorium" uniquely referred to workplaces in which chemical operations were performed: smelting, combustion, distillation, dissolution and precipitation. Artisanal workshops equipped with furnaces and fire in which chemical operations were performed were also known as laboratories. Transmutational alchemy (the transmutation of all base metals into more noble ones, especially gold) was only one aspect of alchemy in the early modern period. The practice of alchemy was also about the chemical production of things--medicines, porcelain, dyes and other products as well as precious metals and about the knowledge of how to produce them. This book uses examples such as the "Uffizi" to discuss how Renaissance courts established spaces where artisanal workshops and laboratories were brought together, thus facilitating the circulation of materials, people and knowledge between the worlds of craft (today s decorative arts) and alchemy. Artisans became involved in alchemical pursuits beyond a shared material culture and some crafts relied on chemical expertise offered by scholars trained as alchemists. Above all, texts and books, products and symbols of scholarly culture played an increasingly important role in artisanal workshops. In these workplaces a sort of hybrid figure was at work. With one foot in artisanal and the other in scholarly culture this hybrid practitioner is impossible to categorize in the mutually exclusive categories of scholar and craftsman. By the seventeenth century the expertise of some glassmakers, silver and goldsmiths and producers of porcelain was just as based in the worlds of alchemical and bookish learning as it was grounded in hands-on work in the laboratory. This book suggests that this shift in workshop culture facilitated the epistemic exchanges between alchemists and producers of the decorative arts."
This book addresses and analyzes the mechanisms responsible for functionality of two technologically relevant materials, giving emphasis on the relationship between structural transitions and electromechanical properties. The author investigates the atomic crystal structure and microstructure by means of thermal analysis, as well as diffraction and microscopy techniques. Electric field-, temperature- and frequency-dependent electromechanical properties are also described. Apart from this correlation between structure and properties, characterization was also performed to bridge between basic research and optimization of application-oriented parameters required for technological implementation. The author proposes guidelines to the reader in order to engineer functional properties in other piezoelectric systems, as well as in other similar functional materials with the perovskite structure.

This book introduces readers to titanium matrix composites (TMCs) with novel network microstructures. The bottleneck problem of extreme brittleness and low strengthening effect surrounding TMCs fabricated by means of powder metallurgy has recently been solved by designing network microstructures, which yield both high strength and superior ductility. As such, network structured TMCs will increasingly offer materials characterized by low weight, high strength, high temperature resistance and superior deformability. The book systematically addresses the design, fabrication, microstructure, properties, modification, and toughening mechanisms of these composites, which will help us find innovative solutions to a range of current and future engineering problems.
This book presents selected papers from the 2nd Workshop on "Durability of Composites in a Marine Environment", which was held in Brest, France in August 2016.

This textbook introduces theoretical piezoelectricity. The second edition updates a classical, seminal reference on a fundamental topic that is addressed in every materials science curriculum. It presents a concise treatment of the basic theoretical aspects of continuum modeling of electroelastic interactions in solids. The general nonlinear theory for large deformations and strong fields is established and specialized to the linear theory for small deformations and weak fields, i.e., the theory of piezoelectricity. Relatively simple and useful solutions of many static and dynamic problems of piezoelectricity that are useful in device applications are given. Emphasis is on the formulation of solutions to problems rather than advanced mathematical solution techniques. This book includes many examples to assist and enhance students' understanding of piezoelectricity and piezoelastics.

This thesis investigates the dielectric properties of metal-oxide ceramics at microwave frequencies. It also demonstrates for the first time that a theory of harmonic phonon coupling can effectively predict the complex permittivity of metal oxides as a function of temperature and frequency. Dielectric ceramics are an important class of materials for radio-frequency, microwave and emergent terahertz technologies. Their key property is complex permittivity, the real part of which permits the miniaturisation of devices and the imaginary part of which is responsible for the absorption of electromagnetic energy. Absorption limits the practical performance of many microwave devices such as filters, oscillators, passive circuits and antennas. Complex permittivity as a function of temperature for low-loss dielectrics is determined by measuring the resonant frequency of dielectric resonators and using the radial mode matching technique to extract the dielectric properties. There have been only a handful of publications on the theory of dielectric loss, and their predictions have often been unfortunately unsatisfactory when compared to measurements of real crystals, sometimes differing by whole orders of magnitude. The main reason for this is the lack of accurate data for a harmonic coupling coefficient and phonon eigenfrequencies at arbitrary q vectors in the Brillouin zone. Here, a quantum field theory of losses in dielectrics is applied, using results from density functional perturbation theory, to predict from first principles the complex permittivity of metal oxides as functions of frequency and temperature.

This book provides an overview of the application of IR spectroscopy in mineralogical investigations, as well as modern trends in the IR spectroscopy of minerals. It includes the most important methodological aspects; characteristic IR bands of different chemical groups and coordination polyhedra; application of IR spectroscopy to the investigation of the crystal chemistry of amphiboles, phyllosilicates, tourmalines etc.; neutral molecules entrapped by microporous minerals; and analysis of hydrogen in nominally anhydrous minerals. About 1600 IR spectra (illustrations as well as a list of wavenumbers) of minerals and some related compounds are accompanied by detailed descriptions of the standard samples used. Each spectrum provides information about the occurrence, appearance, associated minerals, its empirical formula, and unit-cell parameters. The book also provides insights into sample preparation and/or spectrum registration methods. It includes IR spectra of 1020 minerals that were not covered in the book "Infrared spectra of mineral species: Extended library" published in 2014 and written by one of the authors. On average, each page provides information on two minerals/compounds. Subsections correspond to different classes of compounds (silicates, phosphates, arsenates, oxides etc.). About 290 new spectra have been obtained, and the remaining 1310 spectra are taken from most reliable literature sources (published over the last 60 years) and are redrawn in a unified style.

Taking an integrated approach, expert chapters present a wide range of topics, from photocatalysts, solar cells and optics, to thin films and materials for energy storage and conversion, demonstrating the combined use of chemistry, physics, materials science and engineering in the search for solutions to some of the most challenging problems of our time.
This thesis explores the dispersion stability, microstructure and phase transitions involved in the nanoclay system. It describes the recently discovered formation of colloidal gels via two routes: the first is through phase separation and second is by equilibrium gelation and includes the first reported experimental observation of a system with high aspect ratio nanodiscs. The phase behavior of anisotropic nanodiscs of different aspect ratio in their individual and mixed states in aqueous and hydrophobic media is investigated. Distinct phase separation, equilibrium fluid and equilibrium gel phases are observed in nanoclay dispersions with extensive aging. The work then explores solution behavior, gelation kinetics, aging dynamics and temperature-induced ordering in the individual and mixed states of these discotic colloids. Anisotropic ordering dynamics induced by a water-air interface, waiting time and temperature in these dispersions were studied in great detail along with aggregation behavior of nanoplatelets in hydrophobic environment of alcohol solutions.

Interest in ceramics as a high speed cutting tool material is based primarily on favorable material properties. As a class of materials, ceramics possess high melting points, excellent hardness and good wear resistance. Unlike most metals, hardness levels in ceramics generally remain high at elevated temperatures which means that cutting tip integrity is relatively unaffected at high cutting speeds. Ceramics are also chemically inert against most workmetals. This book describes the various classes of ceramic cutting tools and their applications. But more than that, this book is about manufacturing and productivity. Metal cutting, one of man's oldest manufacturing processes (dating back to 1000 B.C. or earlier) assumes a significant role in today's productivity scenario. This is due to significant advances which have been made in both machine tools and cutting tool materials. In terms of manufacturing efficiency the two are inseparable. Advances in technology in one area require that corresponding technical advances be made in the other. In terms of the cutting tool itself, development of more wear resistant tool materials for application in high speed machining has a profound impact on productivity .This increase in cutting speed has been made possible through the progressive evolution of tool materials. The ceramic cutting tool represents a different class of cutting tool material with unique chemical and mechanical properties. Thus, there may be a tendency to avoid the use of ceramic tools where they may be applied advantageously. In order to realize the full potential of ceramics, it is essential to have a clear understanding of all the variables which affect theperformance of these tools. There is not now and probably never will be a "universal" cutting tool material. Many of the new ceramic tool materials today have very specific applications for which they are particularly suited. When properly applied, these new tools can provide the manufacturing engineer with a means of reducing machining costs and increasing productivity. This book breaks new ground in that it introduces the very latest ceramic cutting tool material: chemically vapor deposited diamond coated tools. These tools perform exceptionally well in the machining of aluminum, composites, and other non-ferrous metallic and non-metallic materials. In summary: |
