Book Description
This handy book provides a single, up-to-date source of information for increasing the life of tool steels through optimized design and manufacturing. Supplying a solid understanding of the metallurgy involved, the text explains how material compositions, manufacturing processes, heat treatments, surface hardening techniques, and coatings affect tool steel properties, grades, and performance. It also explores real-life case studies and failure analyses, offering examples of die-life parameters and hints for modifying tool steels and heat treatments during cutting or forming processes. While the book offers deep coverage of properties, microstructure, and manufacturing, its focus is on describing the performance of each application of this special class of ferrous materials.

Book Description
The world of steel is amazingly diverse and so complex that it is not easy to keep track of in practice. In the form of portraits of selected steels and steel groups, this world of steel is to be brought closer to the reader; compact, understandable, informative, structured with examples from practice and suitable for reference. Hot work tool steels are a group of alloyed steels with high hot strength suitable for tools. These can withstand surface temperatures of more than 600 °C in use. For this purpose, they are optimally adapted to the most diverse requirements, especially for tools used in hot forming and die casting. Important are the chemical compositions, methods of production and processing as well as their properties or the material data of hot work tool steels, which are briefly and clearly presented in this book. The contents · The history of hot work tool steels · Designations, chemical compositions, grades, microstructure and properties · Production (melting and powder metallurgy), heat and surface treatments The target groups Trainees in metal professions Students, practitioners, engineers in steel production, forming and production technology, in steel, metal and tool construction and in the steel trade

Book Description
This book is intended to be a reference text on hydrostatic extru sion, a multidisciplinary technology involving the forming process of materials, tribology, high pressure engineering and so forth. Until now only one book bearing the title of hydrostatic extrusion, by Prof. Alexander and Dr. Lengyel, has been published since 1971. Although there are chapters on hydrostatic extrusion in such books as THE MECHANICAL BEHAVIOUR OF MATERIALS UNDER PRESSURE edited by Dr. Pugh, METAL FORMING by Prof. Avitzur and HIGH PRESSURE TECHNOLOGY by Drs. Spain and Paauwe, it is regrettable that no up~to-date reference books on hydro static extrusion are available. As is well known, hydrostatic extrusion is a nearly-ideal lubricated extrusion. Its advantages have been demonstrated by laboratory research in the past two decades, yet many manufacturers, however, still hesitate to adopt the technology in their plants. Their hesitation is certainly due to the lack of exact information on the process and its equipment and also to 'their unfamiliarity with the actual method of operation. In order to provide a useful introduction to the subject for engi neers who work in industries which plan to employ this technique and also to give exact and reliable information on the durability and perfo- ance of production facilities, as well as the capabilities of the process and the properties of extruded products, we decided to publish this book. Starting with theories and computational methods, the processes of cold, warm and hot hydrostatic extrusion are described by experts in their respective fields.

Book Description
The International Symposium "Fatigue under Thermal and Mechanical Loading", held at Petten (The Netherlands) on May 22-24, 1995, was jointly organized by the Institute for Advanced Materials of The Joint Research Centre, E. C. , and by the Societe Fran~se de Metallurgie et de Materiaux. The fast heating and cooling cycles experienced by many high temperature components cause thermally induced stresses, which often operate in combination with mechanical loads. The resulting thermal / mechanical fatigue cycle leads to material degradation mechanisms and failure modes typical of service cycles. The growing awareness that the synergism between the combined thermal and mechanical loads can not be reproduced by means of isothermal tests, has resulted in an increasing interest in thermal and thermo-mechanical fatigue testing. This trend has been reinforced by the constant pull by industry for more performant, yet safer high temperature systems, pushing the materials to the limit of their properties. Dedicated ASTM meetings in particular have set the scene for this area of research. The proceedings of the symposium organized by D. A. Spera and D. F. Mowbray in 1975 provided a reference book on thermal fatigue which reflects the knowledge and experimental capabilities of the mid-seventies.

Book Description
If you are involved with machining or metalworking or you specify materials for industrial components, this book is an absolute must. It gives you detailed and comprehensive information about the selection, processing, and properties of materials for machining and metalworking applications. They include wrought and powder metallurgy tool steels, cobalt base alloys, cemented carbides, cermets, ceramics, and ultra-hard materials. You'll find specific guidelines for optimizing machining productivity through the proper selection of cutting tool materials plus expanded coverage on the use of coatings to extend cutting tool and die life. There is also valuable information on alternative heat treatments for improving the toughness of tool and die steels. All new material on the correlation of heat treatment microstructures and properties of tool steels is supplemented with dozens of photomicrographs. Information on special tooling considerations for demanding applications such as isothermal forging, die casting of metal matrix composites, and molding of corrosive plastics is also included. And you'll learn about alternatives to ferrous materials for metalworking applications such as carbides, cermets, ceramics, and nonferrous metals like aluminum, nickel, and copper base alloys.

Book Description
This book explains the metallurgy of steel and its heat treatment for non-metallurgists. It starts from simple concepts--beginning at the level of high-school chemistry classes--and building to more complex concepts involved in heat treatment of most all types of steel as well as cast iron. It was inspired by the author when working with practicing bladesmiths for more than 15 years. Most chapters in the book contain a summary at the end. These summaries provide a short review of the contents of each chapter. This book is THE practical primer on steel metallurgy for those who heat, forge, or machine steel.

Book Description
Steel and its Heat Treatment: Bofors Handbook describes the fundamental metallographic concepts, materials testing, hardenability, heat treatment, and dimensional changes that occur during the hardening and tempering stages of steel. The book explains the boundaries separating the grain contents of steel, which are the low-angle grain boundaries, the high-angle grain boundaries, and the twinning boundaries. Engineers can determine the hardenability of steel through the Grossman test or the Jominy End-Quench test. Special hardening and tempering methods are employed for steel that are going to be fabricated into tools. The different methods of hardening are manual hardening for a small surface (the tip of a screw); spin hardening for objects with a rotational symmetry (gears with 5 modules or less); and progressive hardening (or a combination with spin hardening) for flat surfaces. The hardening and tempering processes cause changes in size and shape of the substance. The text presents examples of dimensional changes during the hardening and tempering of tool steels such as those occurring in plain-carbon steels and low-alloy steels. The book is a source of reliable information needed by engineers, tool and small equipment designers, as well as by metallurgists, structural, and mechanical engineers.
