The information presented in the Manual was obtained from the literature, from industrial sources, and from a laboratory-scale experimental program designed to study significant forging characteristics of several typical alloys. This information can be divided into four major categories. (1) Plastic deformation of metals: This information deals with the mechanics of plastic deformation, and the fundamental principles of metal behavior during deformation; (2) Principles of forging: This information concerns the empirical relationships developed for forging processes which serve as practical guides for establishing design limits and shop practices; (3) Forging processes and practices: This information relates to the state of the art of forging, and covers such topics as forging equipment, types of operations, die design, lubrications, specifications for typical forged shapes, etc; and (4) Forging alloys: These data treat the forging of specific alloy systems in terms of the influence of material properties on forging behavior, and the influence of forging procedure on the properties of the forged product.

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.

Excerpt from Elementary Forge Practice: A Text-Book for Technical and Vocational Schools While it is realized that a comprehensive knowledge of forge practice can be gained only thru contact with a commercial shop doing a wide variety of work, it is at the same time believed that an understanding of fundamental principles may be secured thru a carefully planned and conducted course of instruction in a technical school. This book is designed to assist the student in grasping fundamental principles. To this end a series of projects involving fundamental operations has been devised. It may be unnecessary for some students to complete the entire set. Some of the earlier projects and occasionally others may be omitted if the student has had previous practice or if he shows great facility. On the other hand it will be readily seen that there is a logical order in the series and that some projects must be mastered before others are undertaken. The whole set may require a longer time than is allotted to the subject in the average manual training course. In such case the instructor may easily select such work as will meet the peculiar conditions. The criticism given an earlier edition by the technical press, and the reception by teachers of forge and machine-shop practice, have shown the need for a text-book of this type. The author wishes to express his appreciation of the assistance rendered by Professor E. P. Lesley of Leland Stanford Junior University, Mr. W. L. Rifenberick, and Mr. H. P. Miller, Jr., in the preparation of this book. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
