Powder Metallurgy Processing: New Techniques and Analyses covers the application of advanced analytical techniques in metallurgy, mechanics, and economics to the fundamentals of powder fabrication processes. The book discusses powder production by gas and water atomization of liquid metals; the triaxial stress state compaction of powders; and the diffusional homogenization of compacted blends of powders. The text also describes the deformation processing of sintered powder materials; the analysis of mechanical property-structure relations in powder forgings; and the economic risk analysis of a miniplant for production of steel strip from powder. Chemical engineers and metallurgists and students taking related courses will find the book invaluable.
Powder metallurgy is a group of advanced processes used for the synthesis, processing, and shaping of various kinds of materials. Initially inspired by ceramics processing, the methodology comprising the production of a powder and its transformation to a compact solid product has attracted attention since the end of World War II. At present, many technologies are availabe for powder production (e.g., gas atomization of the melt, chemical reduction, milling, and mechanical alloying) and its consolidation (e.g., pressing and sintering, hot isostatic pressing, and spark plasma sintering). The most promising methods can achieve an ultra-fine or nano-grained powder structure, and preserve it during consolidation. Among these methods, mechanical alloying and spark plasma sintering play a key role. This book places special focus on advances in mechanical alloying, spark plasma sintering, and self-propagating high-temperature synthesis methods, as well as on the role of these processes in the development of new materials.
This book is a detailed introduction to mechanical alloying, offering guidelines on the necessary equipment and facilities needed to carry out the process and giving a fundamental background to the reactions taking place. El-Eskandarany, a leading authority on mechanical alloying, discusses the mechanism of powder consolidations using different powder compaction processes. A new chapter will also be included on thermal, mechanically-induced and electrical discharge-assisted mechanical milling. Fully updated to cover recent developments in the field, this second edition also introduces new and emerging applications for mechanical alloying, including the fabrication of carbon nanotubes, surface protective coating and hydrogen storage technology. El-Eskandarany discusses the latest research into these applications, and provides engineers and scientists with the information they need to implement these developments. The industrial applications of nanocrystalline and metallic glassy powders are presented. The book also contains over 200 tables and graphs to illustrate the milling processes and present the properties and characteristics of the resulting materials. - Guides readers through each step of the mechanical alloying process, covering best practice techniques and offering guidelines on the required equipment - Tables and graphs are used to explain the stages of the milling processes and provide an understanding of the properties and characteristics of the resulting materials - A comprehensive update on the previous edition, including new chapters to cover new applications

Because of the position of ferrous powder metallurgy, the author deals with the theoretical fundamentals and technical and technological aspects of the current state of knowledge in ferrous powder metallurgy so that special attention may be given to all factors influencing parts and materials with the required properties, form and dimensions, stressing their higher economic efficiency. The book also shows the extensive possibilities for further development of ferrous powder metallurgy and should therefore contribute to increasing the level of general and detailed knowledge of experts working in this area and should help in transition from fabrication of parts by conventional methods with all typical economic and ecological shortcomings to fabrication by powder metallurgy methods.
