This compendium, compiled by two senior engineers from TWI, draws together information from more than 150 individual specifications, covering national, international and industrial toughness requirements for ferritic materials. It covers applications such as pressure vessels, storage tanks, offshore structures, shipping, bridges and pipelines. The data contained in the compendium are derived from over 100 different sources, many of which are not readily available. The book has been designed as a reference source for structural, mechanical, metallurgical and project engineers concerned with structural integrity of welded plant, and will be of especial value to those working in the nuclear, petrochemical and offshore industries.
The Memorandum discusses the current situation on the inclusion of fracture-toughness testing requirements in specifications for high-strength steels used for military applications. The Memorandum was prepared at the request of The Technical Cooperation Program (TTCP), and contains information from Canadian and British members of that program, as well as U.S. information. Military applications discussed include missile motor cases, aircraft landing gear, gun tubes, armor plate, and hydrofoils. (Author).
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 report contains the findings of a study that was performed to establish the variablity of Chappy V-notch (CVN) impact toughness within plates of A572 Grade 50 and A588 steels. The study included plate thickness up to 4 inches meeting AASHTO Zone 3 fracture notch toughness requirements. Both existing literature and the results of research conducted for this study were examined in an attempt to define the variablity in CVN values. The report provides a comprehensive description of the research, including a discussion of the statistical analysis methods used, along with recommended revisions to the AASHTO Guide Specifications for Fracture Critical Non-Redundant Steel Bridge Members. The proposed revisions are intended to provide a reasonable certainty of safe and effective performance of steel plate with respect to toughness. The contents of this report will be of immediate interest and use to bridge engineers, materials engineers, steel bridge fabrication, specification writing bodies, researchers, and others concerned with the design and fabrication of steel bridge elements." --from foreword.
As the shift from the Metal Age progresses, materials engineers and materials scientists seek new analytical and design methods to create stronger and more reliable materials. Based on extensive research and developmental work done at the author’s multi-disciplinary material laboratory, this graduate-level and professional reference addresses the relationship between fracture mechanisms (macroscale) and the microscopic, with the goal of explaining macroscopic fracture behavior based on a microscopic fracture mechanism. A careful fusion of mechanics and materials science, this text and monograph systematically considers an array of materials, from metals through ceramics and polymers, and demonstrates lab-tested strategies to develop desirable high-temperature materials for technological applications.
The report contains the first compilation of available Plane-strain fracture toughness data and is the result of considerable interest during the past few years in developing test methods for obtaining these data. The report is divided into sections on aluminum alloys, high-strength alloy steels, intermediate- and low-strength steels, precipitation-hardening stainless steels, titanium alloys, nickel-base alloy 718, and beryllium.
