Book Description
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.

Book Description
What is heat treatment? This book describes heat treating technology in clear, concise, and nontheoretical language. It is an excellent introduction and guide for design and manufacturing engineers, technicians, students, and others who need to understand why heat treatment is specified and how different processes are used to obtain desired properties. The new Second Edition has been extensively updated and revised by Jon. L. Dossett, who has more than forty years of experience in theat treating operations and management. The update adds important information about new processes and process control techniques that have been developed or refined in recent years. Helpfull appendices have been added on decarburization of steels, boost/diffues cycles for carburizing, and process verification.

Book Description
Heat Treatment Of Steels As An Art To Improve Their Service Performance Has Been Practised Ever Since It Started To Be Used As Tools And Weapons.However, The Scientific Basis Of Heat Treatment Of Steels Became More Apparent Only In The First Half Of This Century And Still Some Gaps Remain In Its Complete Understanding.Earlier Books On Heat Treatment Of Steels Mainly Emphasised The Art And The Empirically Arrived Principles Of Heat Treatment. In The Last Few Decades, Our Understanding Of Phase Transformations And Mechanical Behaviour Of Steels, And Consequently Of Heat Treatment Of Steels, Has Considerably Increased.In This Book On Principles Of Heat Treatment Of Steels The Emphasis Is On The Scientific Principles Behind The Various Heat Treatment Processes Of Steels. Though It Is Expected That The Reader Has Sufficient Background In Phase Transformations And Mechanical Behaviour Of Materials, First Few Chapters Review These Topics With Specific Reference To Steels. Basic Principles Of Various Heat Treatment Processes Of Steels Including Surface Hardening Processes, Are Then Covered In Sufficient Detail To Give A Good Overall Understanding Of These Processes. The Detail Engineering Aspects Are, However, Omitted. These Are Easily Available In Various Handbooks On Heat Treatment. The Book Also Covers Heat Treatment Of Tool Steels And Cast Irons.The Book Has Been Well Written And Can Be Used A Textbook On Heat Treatment For Undergraduate Students. It Is Also A Good Reference Book For Teachers And Researchers In This Area And Engineers In The Industry.

Book Description
Annotation Examines the factors that contribute to overall steel deformation problems. The 27 articles address the effect of materials and processing, the measurement and prediction of residual stress and distortion, and residual stress formation in the shaping of materials, during hardening processes, and during manufacturing processes. Some of the topics are the stability and relaxation behavior of macro and micro residual stresses, stress determination in coatings, the effects of process equipment design, the application of metallo- thermo-mechanic to quenching, inducing compressive stresses through controlled shot peening, and the origin and assessment of residual stresses during welding and brazing.

Book Description
All of the critical technical aspects of gear materials technology are addressed in this new reference work. Gear Materials, Properties, and Manufacture is intended for gear metallurgists and materials specialists, manufacturing engineers, lubrication technologists, and analysts concerned with gear failures who seek a better understanding of gear performance and gear life. This volume complements other gear texts that emphasize the design, geometry, and theory of gears. The coverage begins with an overview of the various types of gears used, important gear terminology, applied stresses and strength requirements associated with gears, and lubrication and wear. This is followed by in-depth treatment of metallic (ferrous and nonferrous alloys) and plastic gear materials. Emphasis is on the properties of carburized steels, the material of choice for high-performance power transmission gearing.
