In the last seven years, following the publication of the first edition of this book, the field of powder metallurgy has produced a number of advanced and useful technologies. In order to make the book relevant and useful to its target readership two new chapters have been added in its second edition. The chapter on Recent Advances in Micro- and Nano-fabrication through Powder Metallurgy deals with the fabrication of micro-grained bulk structure and for manufacturing of nano-sized components using metal and ceramic powders by recent techniques. The chapter on Additive Manufacturing (AM) discusses one of the most exciting innovations in the field of powder metallurgy in recent times. In the last three decades, a number of AM processes have been developed which use either laser sources or electron beams to fuse the metallic or ceramic or composite powders. The book covers most of the recent developments in powder metallurgy such as atomization, mechanical alloying, self-propagating high-temperature synthesis, metal injection moulding, and hot isostatic pressing. Model questions have been given at the end of each chapter. An appendix of relevant terms in powder metallurgy has also been included for ready reference. The book is primarily written for undergraduate and postgraduate students of Metallurgy, Material Science, Mechanical, and Production Engineering, as well as for practicing engineers in the field of powder metallurgy. TARGET AUDIENCE • UG and PG (Metallurgy, Material Science, Mechanical, and Production Engineering) • Practising Engineers in the field of Powder Metallurgy.
