Available in PDF, EPUB and Kindle. Book excerpt: The degree and depth of shock hardening in iron and low-carbon steel plates was experimentally determined by detonating C-3 explosive against the plates. Final hardness levels were not strongly influenced by the magnitude of the pressure above the critical value of 130 kilobars or by explosive thickness or plate thickness, but were dependent upon the original hardness of the plate. The relative widths of the two hardness plateaus through the plates were found to depend upon explosive thickness, plate thickness, and applied pressure; a simple explanation for this dependence is presented in terms of the interac tion of two shocks in the metal. The relationship of hardness and tensile strength was found to be about the same whether hardening was done explosively or by cold-working. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The present needs the past to shape the future. As in many areas of life, heat treatments used in the past have to be studied to understand the present. The resulting conclusions can be used to shape the future. But how did heat treatment develop into a key branch of the economy in spite of its initial inadequacies? This question is the subject of this book, written by Professor Emeritus Dr.-Ing. Hans Berns and published by Härterei Gerster AG. It begins with the production of sponge iron in a bloomery hearth during the pre-Christian era and its subsequent carburisation as an essential requirement for hardening. During the Modern Period, in contrast, the high carbon content of the crude iron had to be painstakingly reduced to a level that allowed forging and hardening. The invention of mild steel in 1856 brought alloyed steels that could be hardened with thicker cross-sections, thus laying the foundations for modern hardening techniques. Härterei Gerster AG, a family business, has become the leading Swiss specialist for technical heat treatments mainly due to ongoing development cooperation with a number of academic institutions. Various development projects established a friendly relationship between Härterei Gerster AG and Prof. Hans Berns.

Download or read book Heat treatment of Steel written by Erik Oberg and published by Pantianos Classics. This book was released on 1914 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amply illustrated and deeply detailed, this classic guide details the creation of grades of steel via heat treatments. It offers fascinating insight into metal manufacturing processes. Since this guidebook was published in 1914, it carries a certain historic value; at the time, the United States economy was undergoing industrialization. Steel was in high demand, and the technology behind its manufacture was improved upon greatly. The metal's importance could not be understated; the expanding rail networks, new multistory constructions, plus tools and factory machines all required huge quantities of quality metal. As we learn, steel is not a simple product: various grades must be achieved via subtle variations in the heat and techniques applied during its manufacture. To articulate his points, the author appends over ninety charts and diagrams of equipment. Together these show how the furnaces work, and how the hardness of the metal is varied to meet strict specifications. Certain intense processes receive their own chapter, such as steel for machine tools and the use of the electric furnace, plus alloys and the testing of the finished products. For its breadth of detail and superb understanding, Erik Oberg's work remains readable over a century since its original publication.

Available in PDF, EPUB and Kindle. Book excerpt: This report is a guide to the literature on high-velocity metalworking. It consists primarily of abstracts of articles, reports, books, and current research projects on and related to high-velocity metalworking arranged according to technical subject. It covers a survey of the reported work in the field up to about October of 1962. Abstracts of over 700 references have been arranged by subject matter, with cross indexing between subjects. There is also an author index. The eleven major subjects and categories covered in the report are: (1) Energy Sources, (2) Energy Transfer Mediums, (3) Facility Requirements, (4) Tooling Requirements, (5) Equipment Requirements, (6) Forming, (7) Hardening, (8) Explosive Welding, (9) Powder Compaction, (10) Metal Removal, and (11) Material Behavior.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Heat Treatment of Steel: Hardening Tempering Case-Hardening In general, any change in the composition of a steel results in some change in its properties. For example, the addition of certain metallic elements to a carbon steel causes, in the alloy steel thus formed, a change in position of the proper hardening temperature point. Tungsten or manganese tend to lower this point, boron and vanadium to raise it; the amount Of the change is practically proportional to the amount of the element added. Just as a small proportion of carbon added to iron produces steel which has decidedly different properties than those found in pure iron, so increasing the proportion of carbon in the steel thus formed, within certain limits, causes a variation in the degree in which these properties manifest themselves. For example, consider the property of tensile strength. In a ten-point carbon steel (one in which there is present but per cent of, carbon) the tensile strength is very nearly 25 per cent greater than that of pure iron. Adding more carbon causes the tensile strength to rise, approximately, at the rate of per cent for each per cent of carbon added. Carbon steels are divided into three classes according to the propor tion of carbon which they contain. The first of these embraces the unsaturated' steels, in which the carbon content is lower than per cent; the second, the saturated steels, in which the proportion of carbon is exactly per cent; and, the third, the supersaturated steels, in which the carbon content is higher than per cent.
