POWDER METALLURGY: SCIENCE, TECH & MATERIALS

The Series in Metallurgy and Materials Science was initiated during the Diamond Jubilee of the Indian Institute of Metals (IIM). In the last decade the progress in the study and development of metallurgy and materials science has been rapid and extensive, giving us a whole new array of materials, with a wide range of applications and a variety of techniques for both processing and characterising them. This book is the first textbook in the series. Since the 1920s modern powder metallurgy has been used to produce a wide range of structural Powder Metallurgy (PM) components, self-lubricating bearings and cutting tools. The conventional method involves the production of metal powders and manufacture of useful objects from such powders by die compaction and sintering. Wrought products are also produced by this route. Powder injection moulding permits the production of stronger, more uniform and more complex PM parts. A detailed discussion of PM materials and products is given in the book. Unique features: Sintering has been elaborated in two chapters-Sintering theory and Sintering technology. Testing and Quality Control of PM Materials and Products, is not found in many PM books.Techno-economics of PM processing are also described in detail. Powder metallurgical aspects of both metallic and ceramic systems are treated equally.Materials handling at various stages of processingPressureless powder shapingFunctionally graded materials, Powder Metallurgy material code, New approach-Pyrophoricity and toxicity in Chapter 3-Nanostructured materials and the electronic theory of sintering in chapter 7. For powder metallurgical engineers-Various kinds of actual testing and quality control methods in Chapter 11-ceramics materials in Chapter 12-Wide range of practically applied parts in Chapter 13. The book is based on the experience of teaching undergraduate and postgraduate engineering students over several years.
