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.

Flame Hardening

Author: Hans Wilhelm Grönegress
Publisher: Springer Science & Business Media
ISBN: 9783642867217
Release Date: 2013-12-11
Genre: Technology & Engineering

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.

Genre: Science

The book comprises three parts. Part 1 gives a historical description of the development of ironworking techniques since the earliest times. Part 2 is the core of the book and deals with the metallurgical basis of microstructures, with four main themes: phase diagrams, solidification processes, diffusion, and solid state phase transformations. Part 3 begins by an introduction to steel design principles. It then goes on to consider the different categories of steels, placing emphasis on their specific microstructural features. Finally, a comprehensive reference list includes several hundred pertinent articles and books. The book is the work of a single author, thus ensuring uniformity and concision. It is intended for scientists, metallurgical engineers and senior technicians in research and development laboratories, design offices and quality departments, as well as for teachers and students in universities, technical colleges and other higher education establishments.

Elementare Neutronenphysik

Author: Karl Wirtz
Publisher: Springer-Verlag
ISBN: 9783662258675
Release Date: 2013-07-02
Genre: Science

Dieses Buch ist aus einer Vorlesung entstanden, die ich seit dem Jahre 1951 gelegentlich an der Universität Göttingen gehalten habe. Sie sollte die Studie renden der Experimentalphysik in die Arbeit eines neutronenphysikalischen Laboratoriums einführen, das sich mit der Messung von Neutronenfluß, Diffu sionslänge, Fermi-Alter, effektiver Neutronentemperatur, Absorptionsquerschnit ten und ähnlichen Problemen befaßt. Die Vorlesung sollte außerdem auf eine anschließende über die Physik der Kernreaktoren vorbereiten. Der ursprüng liche Charakter der Vorlesung wird in dem Buche beibehalten. Es wendet sich an Studierende sowie an alle, die sich mit neutronenphysikalischen Unter suchungen befassen wollen. In der ersten Hälfte wird vorwiegend die Theorie der Neutronenfelder, d. i. im wesentlichen die Diffusions- und Bremstheorie, behandelt. In der zweiten Hälfte handelt es sich vor allem um Messungen in Neutronenfeldern. Der Anhang enthält Angaben und Daten, die nach unserer Erfahrung im Neutronenlabor häufig gebraucht werden. Auf die eigentliche Kernphysik wird in den ersten beiden Kapiteln kurz eingegangen, aber nur so weit, wie es für das Verständnis der folgenden Abschnitte notwendig ist. Die zahlreichen Anwendungen von Neutronenstrahlung werden nicht berührt. In Fragen der Terminologie und der Bezeichnungsweise haben wir uns eng an die englisch-amerikanische Literatur angelehnt. Das einschlägige Schrifttum wurde bis zum Ende des Jahres 1957 berücksichtigt. Es ist jeweils am Ende des betreffenden Kapitels zusammengestellt und nach Möglichkeit in "Allgemeine Literatur" und "Spezielle Arbeiten" unterteilt. Viele Arbeiten sind als Veröffent lichungen der amerikanischen und anderer ausländischer Atomenergiebehörden erschienen und werden mit ihren bekannten Abkürzungen (z. B. AECD) zitiert.

Finally, availability, cost of materials, and environmental regulations all play an important role in selecting the right material for the product.

Metallurgy of Welding

Author: J. F. Lancaster
Publisher: Springer Science & Business Media
ISBN: 9789401095068
Release Date: 2012-12-06
Genre: Technology & Engineering

This book is intended, like its predecessor (The metallurgy of welding, brazing and soldering), to provide a textbook for undergraduate and postgraduate students concerned with welding, and for candidates taking the Welding Institute examinations. At the same time, it may prove useful to practising engineers, metallurgists and welding engineers in that it offers a resume of information on welding metallurgy together with some material on the engineering problems associated with welding such as reliability and risk analysis. In certain areas there have been developments that necessitated complete re-writing of the previous text. Thanks to the author's colleagues in Study Group 212 of the International Institute of Welding, understanding of mass flow in fusion welding has been radically transformed. Knowledge of the metallurgy of carbon and ferritic alloy steel, as applied to welding, has continued to advance at a rapid pace, while the literature on fracture mechanics accumulates at an even greater rate. In other areas, the welding of non-ferrous metals for example, there is little change to report over the last decade, and the original text of the book is only slightly modified. In those fields where there has been significant advance, the subject has become more quantitative and the standard of math ematics required for a proper understanding has been raised.
