This book intended for shop use tries to familiarize the reader with the peculiari ties of a hardening method which due to its many advantages is now in use,many shops. A general knowledge of the principles of hardening and heat treating is presumed. Introduction 1. The name of the process. Flame hardening is a method derived from the old quench hardening and is used for the surface hardening of heat treatable steels. Flame hardening is so named in analogy to flame cutting as the use of a flame is a distinctive feature of this process as opposed to the use of a furnace. 2. Characteristics of flame hardening. In flame hardening the area to be 6 hardened is heated with a burner of large heat capacity (approx. 0.5 · 10 kcaljhr/ meter of flame lengths or 50,000 BTUfhr/inch of flame length) supplied with a mixture of fuel gas and oxygen. The hardening temperature is thus reached in so short a time at the surface that a heat jam is created, that is, more heat is supplied to the surface than can be dissipated to the interior of the workpiece. As the querr ehing takes place immediately after the heating the penetration of the heat to greater depth is prevented and only the outer layer subject to wear is hardened. The core of the workpiece remains unaffected by this heat treatment in cantrast to the other hardening methods where the entire piece is through heated in a furnace.

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.

Steel and Its Heat Treatment, Second Edition presents information, research, and developments in the heat treatment of steel. The book contains chapters that discuss the fundamentals of TTT-diagrams and hardening mechanisms, injection metallurgy and continuous casting, annealing processes, strain aging and temper brittleness. Existing CCT-diagrams are subjected to critical review, the mechanisms controlling hardenability are discussed, and the detailing of the properties of boron constructional steels, micro-alloyed steels and dual-phase steels are also included. Metallurgists, metal workers, and engineers will find the book very useful.
