Annotation A practical selection guide to help engineers and technicians choose the mot efficient surface hardening techniques that offer consistent and repeatable results. Emphasis is placed on characteristics such as processing temperature, case/coating thickness, bond strength, and hardness level obtained. The advantages and limitations of the various thermochemical, thermal and coating/surface modification technologies are compared
The completely revised Second Edition of Metallurgy for the Non-Metallurgist provides a solid understanding of the basic principles and current practices of metallurgy. This major new edition is for anyone who uses, makes, buys or tests metal products. For both beginners and others seeking a basic refresher, the new Second Edition of the popular Metallurgy for the Non-Metallurgist gives an all-new modern view on the basic principles and practices of metallurgy. This new edition is extensively updated with broader coverage of topics, new and improved illustrations, and more explanation of basic concepts. Why are cast irons so suitable for casting? Do some nonferrous alloys respond to heat treatment like steels? Why is corrosion so pernicious? These are questions that can be answered in this updated reference with many new illustrations, examples, and descriptions of basic metallurgy.
Annotation Based on his training in metallurgy and experience in a large British gear manufacturing company, Parrish reviews the microstructural features of metal products that have been carbon case-hardened, and the influence of those features on the more important material properties. He is not concerned with the carbonizing process at all. He primarily addresses students of engineering and ferrous metallurgy, but also stress and design engineers who might want to understand more fully the specifications of the materials they are considering for their designs. He wrote the eight articles to summarize the field's literature of the early 1970s for his own convenience, but at invitation, published them as a series in the Heat Treatment of Metals during 1967-77, and collected them for a first edition of the volume in 1980.

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.
Austenitic stainless steels lend themselves to a wide range of applications. However, they normally stiffer from poor wear resistance and do not respond well to traditional surface treatments. This volume. the fruit of a current status seminar, reflects the enormous strides which have been made in the last few years in the study of the expanded austenite phase (also called the S phase) and the development of new surface treatment techniques. As well as the papers presented at the seminar, the book contains selection from related papers and a comprehensive bibliography of the literature on the subject from 1979 to 2000.
Covers the basics of metal fabrication processes, including primary mill fabrication, casting, bulk deformation, forming, machining, heat treatment, finishing and coating, and powder metallurgy.
Thermochemical surface engineering significantly improves the properties of steels. Edited by two of the world s leading authorities, this important book summarises the range of techniques and their applications. It covers nitriding, nitrocarburizing and carburizing. There are also chapters on low temperature techniques as well as boriding, sheradizing, aluminizing, chromizing, thermo-reactive deposition and diffusion. Reviews the fundamentals of surface treatments and current performance of improved materialsCovers nitriding, nitrocarburizing and carburizing of iron and iron carbon alloysExamines how different thermochemical surface engineering methods can help against corrosion"
