Download or read book An Investigation Into the Susceptibility of Tantalum and Vanadium to Slow Strain Rate Embrittlement Due to Oxygen Nitrogen and Carbon written by R. E. Reed-Hill and published by . This book was released on 1980 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomena of slow strain-rate embrittlement was studied in three metal-interstitial systems, tantalum-oxygen, vanadium-oxygen and tantalum-nitrogen. The embrittlement of tantalum by oxygen was investigated on specimens containing four levels of oxygen -- 0.33, 0.50, 0.85 and1.30 atomic percent. All of the compositions showed embrittlement between 500-1000K in specimens deformed at epsilon = 8.8 x 10 to the 4th power sec to the minus one power. Associated with the embrittling phenomenon, and occurring in the same temperature range where the ductility is dropping, and three dynamic strain-aging effects: (a) a yield stress plateau from 300-600K, (b) serrated yielding from 453-600K and an increasing work hardening rate from 300-600K; Scanning electron microscope studies show that failures were by microvoid coalescence at low temperatures changing to a predominantly intergranular mode in the embrittlement range. Study of the vanadium-oxygen system also showed an embrittlement region between 600-875K. This embrittlement was accompanied by a yield stress plateau between 400-600K, an increasing work hardening rate between 300-650K and serrated yielding from 525K to 650K. A high level of titanium impurity limited testing to low oxygen concentrations. Tests on the tantalum-nitrogen system concluded that nitrogen did not produce slow strain-rate embrittlement in this metal although it served as a potent room temperature strengthener. The interval in which embrittlement is expected in this metal is at a sufficiently high temperature that dynamic recovery and sofening take place. (Author).

Download or read book Oxidation of Intermetallics written by Hans Jürgen Grabke and published by John Wiley & Sons. This book was released on 2008-07-11 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last ten years vast efforts were made in the research and development of intermetallic compounds to attain improved high temperature strength and low temperature ductility. These new structural materials are used in several high-temperature applications like engines and turbines. Oxidation and corrosion resistance are as important for the current applications of these materials as mechanical properties. This book gives a sound review of the present knowledge of the oxidation kinetics and mechanisms of intermetallics. Especially Ti-, Ni- and Fe-aluminides are treated in detail by experts from Europe, USA and Japan. The information provided will be of wealth for any engineer and scientist- materials scientist, physicist or chemist - involved in the development of new intermetallic materials and their applications.

Download or read book Combustion for Material Synthesis written by Alexander S. Rogachev and published by CRC Press. This book was released on 2014-12-15 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the state of the art in combustion synthesis of advanced materials. It is a first attempt to summarize and critically review in one monograph the mechanisms of combustion and product structure formation for a variety of systems, including nanosystems. The authors discuss a wide range of topics including phenomenology, theory, and modern in-situ experimental approaches to investigate the heterogeneous self-sustained reactions, as well as properties of the product synthesized, and methods for large-scale materials production.

Download or read book Chemical Metallurgy written by Chiranjib Kumar Gupta and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 831 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical metallurgy is a well founded and fascinating branch of the wide field of metallurgy. This book provides detailed information on both the first steps of separation of desirable minerals and the subsequent mineral processing operations. The complex chemical processes of extracting various elements through hydrometallurgical, pyrometallurgical or electrometallurgical operations are explained. In the choice of material for this work, the author made good use of the synergy of scientific principles and industrial practices, offering the much needed and hitherto unavailable combination of detailed treatises on both compiled in one book.

Download or read book Rare Metal Technology 2020 written by Gisele Azimi and published by Springer Nature. This book was released on 2020-01-20 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection presents papers from a symposium on extraction of rare metals as well as rare extraction processing techniques used in metal production. Rare metals include strategic metals that are in increasing demand and subject to supply risks. Metals represented include neodymium, dysprosium, scandium and others; platinum group metals including platinum, palladium, iridium, and others; battery related metals including lithium, cobalt, nickel, and aluminum; electronics-related materials including copper and gold; and refectory metals including titanium, niobium, zirconium, and hafnium. Other critical materials such as gallium, germanium, indium and silicon are also included. Papers cover various processing techniques, including but not limited to hydrometallurgy (solvent extraction, ion exchange, precipitation, and crystallization), electrometallurgy (electrorefining and electrowinning), pyrometallurgy, and aeriometallurgy (supercritical fluid extraction). Contributions are focused on primary production as well as secondary production through urban mining and recycling to enable a circular economy. ​A useful resource for all involved in commodity metal production, irrespective of the major metal Provides knowledge of cross-application among industries Extraction and processing of rare metals that are the main building block of many emerging critical technologies have been receiving significant attention in recent years. The technologies that rely on critical metals are prominent worldwide, and finding a way to extract and supply them effectively is highly desirable and beneficial.
