Mechanical Properties and Working of Metals and Alloys

This book is intended to serve as core text or handy reference on two key areas of metallic materials: (i) mechanical behavior and properties evaluated by mechanical testing; and (ii) different types of metal working or forming operations to produce useful shapes. The book consists of 16 chapters which are divided into two parts. The first part contains nine chapters which describe tension (including elastic stress – strain relation, relevant theory of plasticity, and strengthening methods), compression, hardness, bending, torsion – pure shear, impact loading, creep and stress rupture, fatigue, and fracture. The second part is composed of seven chapters and covers fundamentals of mechanical working, forging, rolling, extrusion, drawing of flat strip, round bar, and tube, deep drawing, and high-energy rate forming. The book comprises an exhaustive description of mechanical properties evaluated by testing of metals and metal working in sufficient depth and with reasonably wide coverage. The book is written in an easy-to-understand manner and includes many solved problems. More than 150 numerical problems and many multiple choice questions as exercise along with their answers have also been provided. The mathematical analyses are well elaborated without skipping any intermediate steps. Slab method of analysis or free-body equilibrium approach is used for the analytical treatment of mechanical working processes. For hot working processes, different frictional conditions (sliding, sticking and mixed sticking–sliding) have been considered to estimate the deformation loads. In addition to the slab method of analysis, this book also contains slip-line field theory, its application to the static system, and the steady state motion, Further, this book includes upper-bound theorem, and upper-bound solutions for indentation, compression, extrusion and strip drawing. The book can be used to teach graduate and undergraduate courses offered to students of mechanical, aerospace, production, manufacturing and metallurgical engineering disciplines. The book can also be used for metallurgists and practicing engineers in industry and development courses in the metallurgy and metallic manufacturing industries.

Amit Bhaduri is a faculty member in the Department of Metallurgical and Materials Engineering at IIT Kharagpur, where he has taught since 1984, prior to which he was a lecturer at Regional Engineering College, Durgapur (presently, National Institute of Technology, Durgapur). He has earned his B.E. and M. Tech in Metallurgical Engineering from University of Calcutta and IIT Kanpur, respectively. He was awarded with the ‘Indranil Award’ from the Mining, Geological and Metallurgical Institute of India as well as other awards and prizes for his subject knowledge. He has over 34 years of teaching experience, over the course of which he has taught several subjects. His special focus has been on teaching ‘Mechanical Testing of Materials’ and ‘Mechanical Working of Materials’, which he has taught for about 20 years and 10 years respectively at IIT Kharagpur.
