The only handbook of mathematical relations with a focus on particulate materials processing The National Science Foundation estimates that over 35% of materials-related funding is now directed toward modeling. In part, this reflects the increased knowledge and the high cost of experimental work. However, currently there is no organized reference book to help the particulate materials community with sorting out various relations. This book fills that important need, providing readers with a quick-reference handbook for easy consultation.This one-of-a-kind handbook gives readers the relevant mathematical relations needed to model behavior, generate computer simulations, analyze experiment data, and quantify physical and chemical phenomena commonly found in particulate materials processing. It goes beyond the traditional barriers of only one material class by covering the major areas in ceramics, cemented carbides, powder metallurgy, and particulate materials. In many cases, the governing equations are the same but the terms are material-specific. To rise above these differences, the authors have assembled the basic mathematics around the following topical structure: Powder technology relations, such as those encountered in atomization, milling, powder production, powder characterization, mixing, particle packing, and powder testing Powder processing, such as uniaxial compaction, injection molding, slurry and paste shaping techniques, polymer pyrolysis, sintering, hot isostatic pressing, and forging, with accompanying relations associated with microstructure development and microstructure coarsening Finishing operations, such as surface treatments, heat treatments, microstructure analysis, material testing, data analysis, and structure-property relations Handbook of Mathematical Relations in Particulate Materials Processing is suited for quick reference with stand-alone definitions, making it the perfect complement to existing resources used by academic researchers, corporate product and process developers, and various scientists, engineers, and technicians working in materials processing.

Although sintering is an essential process in the manufacture ofceramics and certain metals, as well as several other industrialoperations, until now, no single book has treated both thebackground theory and the practical application of this complex andoften delicate procedure. In Sintering Theory and Practice, leadingresearcher and materials engineer Randall M. German presents acomprehensive treatment of this subject that will be of great useto manufacturers and scientists alike. This practical guide to sintering considers the fact that while thebonding process improves strength and other engineering propertiesof the compacted material, inappropriate methods of control maylead to cracking, distortion, and other defects. It provides aworking knowledge of sintering, and shows how to avoid problemswhile accounting for variables such as particle size, maximumtemperature, time at that temperature, and other problems that maycause changes in processing. The book describes the fundamental atomic events that govern thetransformation from particles to solid, covers all forms of thesintering process, and provides a summary of many actual productioncycles. Building from the ground up, it begins with definitions andprogresses to measurement techniques, easing the transition,especially for students, into advanced topics such as single-phasesolid-state sintering, microstructure changes, the complications ofmixed particles, and pressure-assisted sintering. German draws onsome six thousand references to provide a coherent and lucidtreatment of the subject, making scientific principles andpractical applications accessible to both students andprofessionals. In the process, he also points out and avoids thepitfalls found in various competing theories, concepts, andmathematical disputes within the field. A unique opportunity to discover what sintering is all about--bothin theory and in practice What is sintering? We see the end product of this thermal processall around us--in manufactured objects from metals, ceramics,polymers, and many compounds. From a vast professional literature,Sintering Theory and Practice emerges as the only comprehensive,systematic, and self-contained volume on the subject. Covering all aspects of sintering as a processing topic, includingmaterials, processes, theories, and the overall state of the art,the book* Offers numerous examples, illustrations, and tables that detailactual processing cycles, and that stress existing knowledge in thefield* Uses the specifics of various consolidation cycles to illustratethe basics* Leads the reader from the fundamentals to advanced topics,without getting bogged down in various mathematical disputes overtreatments and measurements* Supports the discussion with critically selected references fromthousands of sources* Examines the sintering behavior of a wide variety of engineeredmaterials--metals, alloys, oxide ceramics, composites, carbides,intermetallics, glasses, and polymers* Guides the reader through the sintering processes for severalimportant industrial materials and demonstrates how to controlthese processes effectively and improve present techniques* Provides a helpful reference for specific information onmaterials, processing problems, and concepts For practitioners and researchers in ceramics, powder metallurgy,and other areas, and for students and faculty in materials scienceand engineering, this book provides the know-how and understandingcrucial to many industrial operations, offers many ideas forfurther research, and suggests future applications of thisimportant technology. This book offers an unprecedented opportunity to explore sinteringin both practical and theoretical terms, whether at the lab or inreal-world applications, and to acquire a broad, yet thorough,understanding of this important technology.

The field of powder-binder shaping is growing to reach levels of great commercial significance. Shaping technologies based on powder-binder formulations apply to a broad array of engineering components and even reach into medical implants and aerospace components. Powder-binder formulations have also evolved in the form of additive manufacturing, allowing component production without tooling.This fundamental and practical guide focuses on the basic principles and options available for the application of polymers and natural organics to powder processing. It links the material, powder characteristics, forming process, and product attributes together to give the first unified treatment on polymer assisted powder processing.The processes discussed include uniaxial die compaction, injection molding, tape casting, extrusion, slip casting, slurry casting, and additive manufacturing. In each process, the technical requirements are outlined and the polymer candidates are identified. This book bridges the practical aspects of cost, availability, and safety with fundamental structure, properties, processing, and tests. Each chapter concludes with a review of current industrial standards and examples of practices.

This book is focused on composites involving powders as the starting materials. It provides relevant information for questions related to the selection of constituent phases, most economic fabrication routes, proper testing procedures, and product optimization. The field is sufficiently advanced that predictive models guide many decisions. Applications are illustrated over a broad range of material and property combinations. This title includes:•Selection of phases with consideration of intersolubility & interface•Microstructure, especially the role of phase connectivity•Fabrication approaches, especially net-shape consolidation•Assessment of typical properties, testing techniques & industry standards•Design & trade-off decisions involved in optimization, including cost•Applications, both those that have matured and some emerging prospects.The reader may have little appreciation for how particulate composites are literallyeverywhere. Examples include new wear resistant consumer products(Apple watch), longer lasting automotive tires with reduced rolling resistance(Yokohama tires), and new diamond heat sinks for computers(Element Six substrates). Particulate composites also form critical components in applications such as magnets, dental fillings, brakes, darts, bio-implants, & cutting tools. Particulate composites are a multi-billion dollar industry, and can be a cost-effective solution ripe for innovation and continued rapid growth. For the engineer, the wide range of particulate composite formulation and property combinations offers the ability to design for a variety of application and provides ample opportunity for innovation.Particulate Composites: Fundamentals & Applications is ideal for use in a one-semester eng. course at the senior UG/graduate level, and is also suitable as a practical reference for materials scientists in academia and industry.
