Bonding Theory for Metals and Alloys, 2e builds on the success of the first edition by introducing new experimental data to each chapter that support the breakthrough "Covalon" Conduction Theory developed by Dr. Wang. Through the recognition of the covalent bond in coexistence with the 'free' electron band, the book describes and demonstrates how the many experimental observations on metals and alloys can all be reconciled. Subsequently, it shows how the individual view of metals and alloys by physicists, chemists and metallurgists can be unified. This book covers such phenomena as the Miscibility Gap between two liquid metals, phase equilibrium, superconductivity, superplasticity, liquid metal embrittlement, and corrosion. The author also introduces a new theory based on 'Covalon' conduction, which forms the basis for a new approach to the theory of superconductivity. Bonding Theory for Metals and Alloys, 2e is of interest to physical and theoretical chemists alongside engineers working in research and industry, as well as materials scientists, physicists, and students at the upper undergraduate and graduate level in these fields.

High-Entropy Alloys, Second Edition provides a complete review of the current state of the field of high entropy alloys (HEA). Building upon the first edition, this fully updated release includes new theoretical understandings of these materials, highlighting recent developments on modeling and new classes of HEAs, such as Eutectic HEAs and Dual phase HEAs. Due to their unique properties, high entropy alloys have attracted considerable attention from both academics and technologists. This book presents the fundamental knowledge, the spectrum of various alloy systems and their characteristics, key focus areas, and the future scope of the field in terms of research and technological applications.

Metals, Minds and Mobility' seeks to integrate archaeometallurgical data with archaeological theory to address longstanding questions about mechanisms of exchange, mobility and social complexity in prehistory. The circulation of metal has long been viewed as a catalyst for social, economic and population changes in Europe. New techniques and perspectives derived from archaeological science can shed new light on the understanding of the movement of people, materials and technological knowledge. In recent years these science-based approaches have situated mobility at the forefront of the archaeological debate. Advances in the characterisation of metals and metallurgical residues combined with more sophisticated approaches to data analysis add greater resolution to provenance studies. 0Though offering better pictures of artefact source, the explanation of artefact distribution across geographic space requires the use of theoretically informed models and solid archaeological evidence to discern differences between the circulation of raw materials, ingots, objects, craftspeople and populations. Bringing together many leading expert contributions address topics that include the invention, innovation and transmission of metallurgical knowledge; archaeometric based models of exchange; characterization and discrimination of different modes of material circulation; and the impact of metals on social complexity.0The 13 papers are organised in three main sections dealing with key debates in archaeology: transmission of metallurgical technologies, knowledge and ideas; prestige economies and exchange; and circulation of metal as commodities and concludes with a review current approaches, situating the volume in a broader context and identifying future research directions.

Dieser Band ist ein handliches Übersichtswerk über die früheste Stahlgewinnung. Ausgehend von sensationellen Funden aus der Römerstadt Augusta Raurica bei Basel, kommt der Autor zum Schluss, dass hier am Rheinknie, in der römischen Provinz Obergermanien, schon bald nach der römischen Eroberung, d. h. ab dem frühen 1. Jahrhundert n. Chr., härtbarer Stahl aus »Weicheisen« erzeugt worden ist. Analoge Funde aus dieser Zeit und Region kannte man bisher noch nicht!Der Hauptwert dieses Buches ist ein ausführlicher Überblick über alle bekannten Stahlerzeugungstechniken, die lange vor der Industrialisierung entwickelt und angewendet worden sind. Am Beispiel etwa des indischen »Tiegelstahls« oder des römischen »ferrum Noricum« (steirischer Stahl) werden archäologische, metallurgische und schriftliche Quellen beigezogen und vorgestellt.Anlass zur neuen Untersuchung waren die römischen Funde aus Augusta Raurica. Sie werden im zweiten Teil der Publikation archäologisch untersucht und präsentiert. Analysen ergaben, dass Reste von gebrannten Lehmumhüllungen vorliegen, in denen kleine Eisenbarren der Hitze ausgesetzt worden sind.Rezepte aus dem Mittelalter und der frühen Neuzeit, sowie ganz ähnliche, aber jüngere Funde aus der Wikingerzeit in Skandinavien legen nahe, dass in den Umhüllungen Eisen »aufgekohlt«, d. h. zuStahl umgewandelt worden sein muss.Um diese Interpretation zu erhärten, wurde der von den Untersuchungsbefunden abgeleitete Prozess mit Hilfe der »Experimentellen Archäologie« nachvollzogen.Ein Vorbild interdisziplinärer Vorgehensweise: Geschichte und Technik, Befund und Experiment, Beobachtung und Analyse, Schriftquellen und Technologie, Archäologie und Industrie.

Afin d'étudier la métallurgie ancienne, les auteurs utilisent beaucoup l'archéologie expérimentale comme outil de recherche. Ce volume rassemble différentes approches méthodologiques. L'intégration de la fouille archéologique, de l'archéométrie et de l'archéologie expérimentale concourt à définir une méthode, développée à partir de ces différentes perspectives. Dans le cadre d'une recherche holistique en archéométallurgie, la restitution expérimentale a démontré son potentiel en tant qu'outil de recherche, transposable aux études technologiques anciennes. Nous espérons que ce volume, qui combine aspects théoriques et études de cas spécifiques, pourra inspirer des lecteurs d'horizons et d'intérêts très divers. En particulier, nous visons à convaincre nos collègues - qui étudient également la métallurgie ancienne et qui n'ont pas encore envisagé l'archéologie expérimentale - d'intégrer dans leurs protocoles ce puissant outil de recherche pour de futurs travaux.
