This book is an attempt to explain hardness measurements of metals in terms of some of their more basic physical properties. The intention is to provide, for physicists, engineers, and metallurgists, a better understanding of what hardness means and what hardness measurements imply. The author emphasises the physical concepts involved, so that non-mathematical readers can grasp and appreciate the general physical picture without needing to follow the more detailed mathematical treatment.

Discover a novel approach to the subject, providing detailed information about established and innovative mechanical testing procedures.

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.

This book provides a comprehensive overview of hardness testing, including the various methods and equipment used, testing applications and the selection of testing methods. The revised and updated second edition features expanded information on microhardness testing, specialized hardness tests, and hardness testing standards. Contents: Introduction to Hardness Testing Brinell Testing Rockwell Hardness Testing Vickers Hardness Testing Microhardness Testing Scelroscope and Leeb Hardness Testing Hardness Testing Application Selection of Hardness Testing Materials Appendices Index.

David A. Scott provides a detailed introduction to the structure and morphology of ancient and historic metallic materials. Much of the scientific research on this important topic has been inaccessible, scattered throughout the international literature, or unpublished; this volume, although not exhaustive in its coverage, fills an important need by assembling much of this information in a single source. Jointly published by the GCI and the J. Paul Getty Museum, the book deals with many practical matters relating to the mounting, preparation, etching, polishing, and microscopy of metallic samples and includes an account of the way in which phase diagrams can be used to assist in structural interpretation. The text is supplemented by an extensive number of microstructural studies carried out in the laboratory on ancient and historic metals. The student beginning the study of metallic materials and the conservation scientist who wishes to carry out structural studies of metallic objects of art will find this publication quite useful.

High Temperature Metallography focuses on the reactions, processes, methodologies, and approaches involved in high temperature metallography. The publication first offers information on the basic principles of high temperature vacuum metallography, including the methods of heating test specimens in vacuo to high temperatures; specimens for investigating structure and properties of metals by heating in vacuo; and methods of regulating and controlling the temperature of specimens heated in vacuo. The text then ponders on vacuum systems in equipment for investigating the structure and properties of metals and alloys heated at low ultimate pressures, as well as gas flow through the tubes during evacuation; construction and characteristics of vacuum pumps used for high temperature metallography equipment; and approximate calculation of parameters of vacuum systems for equipment intended for investigating metals during heating in a vacuum. The book takes a look at equipment and instruments for investigating metals heated in a vacuum; method of investigation by studying microstructures and properties of metals and alloys while heated in vacuo; and methods for measuring elasticity, internal friction, and hardness, and for investigating the deformation of metals and alloys at high temperatures in vacuo. The text is a dependable reference for readers interested in high temperature metallography.

Surface Engineering of Metals provides basic definitions of classical and modern surface treatments, addressing mechanisms of formation, microstructure, and properties of surface layers. Part I outlines the fundamentals of surface engineering, presents the history of its development, and proposes a two-category classification of surface layers. Discussions include the basic potential and usable properties of superficial layers and coatings, explaining their concept, interaction with other properties, and the significance of these properties for proper selection and functioning. Part II provides an original classification of the production methods of surface layers. Discussions include the latest technologies in this field, characterized by directional or beam interaction of particles or of the heating medium with the treat surface.
