As sintering applications march toward a $30 billion global business, the models for sintering have progressed, but generally follow behind observation. Documentation of the steps needed to build to a quantitative and predictive theory are often missed. Sintering: From Empirical Observations to Scientific Principles partitions sintering applications and observations to show critical turning points required to establish modern sintering as a predictive science. This book, written by the most cited author in his field, is laced with people, organizations, critical steps, and important formulations in a mixture of history, personalities, and applications. Exploring how insights in seemingly unrelated fields sparked progress, it is also a teaching tool to show where there is success, where there are problems, and how to organize teams to leapfrog to new applications or plateaus of use. Randall German's Sintering: From Empirical Observations to Scientific Principles is a platform for directly addressing the critical control parameters in these new research and development efforts. - Shows how the theories and understanding of sintering were developed and improved over time, and how different products were developed, ultimately leading to important knowledge and lessons for solving real sintering problems - Covers all the necessary infrastructure of sintering theory and practice, such as atomic theory, surface energy, microstructure, and measurement and observation tools - Introduces the history and development of such early sintered products as porcelain, tungsten lamp filaments, bronze bearings, steel automotive components, platinum crucibles and more
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.
