Steels are a class of materials with multiple and complicated transformations; this is true even for steels of the basic cutlery industry. A damascus steel is a fascinating subject to study, rich in multiple facets, that appears in a first approach as a composite material artistically exploited. Damacus steel was developed in the first millennium AD in India or Sri-Lanka. Its reputation is related to its exceptional properties and to the moire pattern. A similar damask pattern could be obtained by forge-welding giving rise to controversies. Recent findings allow a better understanding of this pattern formation. This book presents firstly, observations of ancient blade samples examined with modern technologies such as electron microscopy. The features of many typical swords from different periods are discussed: Celtic, Merovingian, Viking and oriental wootz swords, Persian shamshirs, Japanese katana, rapiers etc. In the second part, microstructural observations at different levels of magnification are displayed and their interpretation is discussed in detail, thus revealing the secret of sophisticated forgings. One chapter is devoted to introducing the main transformations undergone by these steels during the forging processes. The book is intended for all those people interested in the history of science and more specifically to the metallurgists, to the archaeologists and all the researchers confronted with the problems of the expertise of the vestiges, to the blacksmiths, and to the collectors of valuable artistic blades. Madeleine Durand-Charre has taught structural metallurgy at the Polytechnic Institute of Grenoble and at the University Joseph Fourier of Grenoble. Her research work concerned microstructure formation and determination of phase equilibria. She investigated complex alloys such as superalloys and steels. Her work on vanadium cast irons was awarded the Vanadium Shield in 1989 from the Institute of Metals. She is author of several books and articles in metallurgy.

Damascus steel: centuries-old, hot-forged steel that is legendary for making sharp, strong blades that struck fear in many a mans heart. Artisans, blacksmiths, and hobbyists the world over have initiated a renaissance of this fascinating, decorative material, which is the focus of this comprehensive book. Unravel the history and mysteries surrounding various types of Damascus steel before delving into the theory and mechanics of forging your own complex Damascus steel creations. Use the detailed, computer-generated illustrations and hundreds of photos to learn how to forge-weld your Damascus steel billets, properly execute torsion technique, and see the endless potential for forging patterns in Damascus steel. Complete with material and equipment requirements, safety precautions, practical tips, temperature charts, and examples of finished works, this book offers inspiration and the fundamentals of working in this ancient medium. Ideal for amateur blacksmiths and experienced metalworkers. Includes a bonus poster, "Practical Tips for the Blacksmith."
Pattern-welded blades are among the most beautiful and durable creations ever to emerge from the bladesmith's forge. Now, Jim Hrisoulas, reveals the secrets of this ancient craft, from the welding of the starting billet to the final assembly of the completed blade.
Although it is fashionable among modernists to claim that globalism emerged only since ca. 1800, the opposite can well be documented through careful comparative and transdisciplinary studies, as this volume demonstrates, offering a wide range of innovative perspectives on often neglected literary, philosophical, historical, or medical documents. Texts, images, ideas, knowledge, and objects migrated throughout the world already in the pre-modern world, even if the quantitative level compared to the modern world might have been different. In fact, by means of translations and trade, for instance, global connections were established and maintained over the centuries. Archetypal motifs developed in many literatures indicate how much pre-modern people actually shared. But we also discover hard-core facts of global economic exchange, import of exotic medicine, and, on another level, intensive intellectual debates on religious issues. Literary evidence serves best to expose the extent to which contacts with people in foreign countries were imaginable, often desirable, and at times feared, of course. The pre-modern world was much more on the move and reached out to distant lands out of curiosity, economic interests, and political and military concerns. Diplomats crisscrossed the continents, and artists, poets, and craftsmen traveled widely. We can identify, for instance, both the Vikings and the Arabs as global players long before the rise of modern globalism, so this volume promises to rewrite many of our traditional notions about pre-modern worldviews, economic conditions, and the literary sharing on a global level, as perhaps best expressed by the genre of the fable.
David A. Scott provides a detailed introduction to the structure and morphology of ancient and historic metallic materials. Much of the scientific research on this important topic has been inaccessible, scattered throughout the international literature, or unpublished; this volume, although not exhaustive in its coverage, fills an important need by assembling much of this information in a single source. Jointly published by the GCI and the J. Paul Getty Museum, the book deals with many practical matters relating to the mounting, preparation, etching, polishing, and microscopy of metallic samples and includes an account of the way in which phase diagrams can be used to assist in structural interpretation. The text is supplemented by an extensive number of microstructural studies carried out in the laboratory on ancient and historic metals. The student beginning the study of metallic materials and the conservation scientist who wishes to carry out structural studies of metallic objects of art will find this publication quite useful.
An in-depth exploration of the effects of different steels, heat treatments, and edge geometries on knife performance. This book provides ratings for toughness, edge retention, and corrosion resistance for all of the popular knife steels. Micrographs of over 50 steels. Specific recommended heat treatments for each steel. And answers to questions like: 1) Does a thinner or thicker edge last longer? 2) What heat treatment leads to the best performance? 3) Are there performance benefits to forging blades? 4) Should I use stainless or carbon steel? All of these questions and more are answered by a metallurgist who grew up around the knife industry.
This title surveys some 60 examples of swords made and used in northern Europe during the Viking Age, from the mid 8th to the mid-11th century. It contains an illustrated overview of blade types and construction, pattern-welding, inscriptions and handle forms and Jan Petersen's classification.
