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.
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.
Infanticide is one of the most common, yet least understood of all human crimes. Although academic articles document isolated aspects of this problem, a single, unified analysis of infanticide has not been completed until now. In Hardness of Heart/Hardness of Life, Larry Milner provides the first exhaustive survey of infanticide, drawing on historical data from around the world. He then uses this survey as a basis for investigating why infanticide has been present in every form of human society throughout history. Both comprehensive and compelling, this important study will intrigue students of human psychology, social welfare, and child abuse, and will promote further research on this alarmingly overlooked atrocity.
A comprehensive treatment of the chemistry and physics of mechanical hardness Chemistry and Physics of Mechanical Hardness presents a general introduction to hardness measurement and the connections between hardness and fundamental materials properties. Beginning with an introduction on the importance of hardness in the development of technology, the book systematically covers: Indentation Chemical bonding Plastic deformation Covalent semiconductors Simple metals and alloys Transition metals Intermetallic compounds Ionic crystals Metal-metalloids Oxides Molecular crystals Polymers Glasses Hot hardness Chemical hardness Super-hard materials Chemistry and Physics of Mechanical Hardness is essential reading for materials scientists, mechanical engineers, metallurgists, ceramists, chemists, and physicists who are interested in learning how hardness is related to other properties and to the building blocks of everyday matter.
The 17 peer-reviewed papers describe investigations where the precision of test procedures were either examined (to study the precision) or enhanced (to increase the precision). Topics include hardness testing, fatigue and fracture testing, and specimen alignment and gripping problems. Annotation co
