Powder Metallurgy Science, Technology, and Materials

Since the 1920s, modern powder metallurgy has been used to produce a wide range of structural powder metallurgy components, self-lubricating bearings, and cutting tools. The conventional method involves the production of metal powders and the manufacture of useful objects from such powders by die compaction and sintering. Powder injection molding permits the production of stronger, more uniform, and more complex powder metallurgy parts. A detailed discussion of powder metallurgy materials and products is given in this book. Worked examples, exercises, questions, and problems are included in each chapter.

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.
