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 processing
- Pressureless powder shaping
- Functionally 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. It serves as a textbook (both for undergraduate and postgraduate courses in engineering) and also as a handy reference book for engineers in the PM industry. In order to aid and broaden the problem-solving capability of students, worked examples are included in each chapter. In the end of chapter exercises, a variety of questions and problems are included.
Dr Anish Upadhyaya, Associate Professor, Department of Materials Science and Engineering, IIT Kanpur, Kanpur, has been an advocate of powder metallurgical processing due to its high materials utilisation, near net-shaping and energy efficiency. He has done pioneering work in the area of microwave sintering of metallic systems and has been conferred several awards, including Metallurgist of the Year (2009) from Ministry of Steel, Government of India, and has has co-authored a book, Materials Science and Engineering.
Dr GS Upadhyaya, Retired Professor, Department of Materials and Metallurgical Engineering, IIT Kanpur, Kanpur, has made significant contributions to sintering science and technology through his research. He has published more than 300 original papers and authored/edited 14 books on sintered materials. He has trained a large number of students in powder metallurgy, who are now working in academia, research and industry. He is a materials consultant based in Varanasi, India.
