Book excerpt: Tungsten has been used for many years by the electrical and electronic industries in the form of small component parts such as filaments, electrodes, grids, contacts, and various other items. These very specialized applications were basically due to the high-temperature properties of this metal. More recently, due to the high melting point of tungsten as well as its exceptional high-temperature strength, interest has been focused on the production of much larger sections for specialized structural applications. These large size ingots, billets, and special shapes are rapidly becoming available and are being incorporated in very specialized designs. The main factors limiting the extensive use of tungsten are its lack of oxidation resistance in air at elevated temperatures, its high density, and the problem of fabricating the consolidated metal. In each of these problems, noticeable progress is being made, especially in fabrication techniques. An excellent summary of the fabrication of tungsten was recently published by Barth.

Book excerpt: Government-sponsored tungsten research and development efforts encompass a broad rage of technological activities. Typifying the extreme limits of efforts since January, 1960, studies have ranged from preparation of unalloyed metal to development of high-integrity fabricated shapes of tungsten-base materials. Nine major areas outline the broad over-all effort, and each is summarized within this report by brief technical discussions of 104 separate studies on 79 research programs. Included are preparation of metal, consolidation, primary and secondary working, joining, fabrication and performance of rocket nozzles, oxidation and other high-temperature reactions, protective coatings, properties, and physical metallurgy.

Download or read book Tungsten and Its Compounds written by G. D. Rieck and published by Elsevier. This book was released on 2013-10-22 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tungsten and Its Compounds is a three-chapter text that explores the history, properties, production, and use of tungsten and its related compounds. The first chapter deals with the discovery, applications, ore occurrence, and production of tungsten. The second chapter describes the physico-chemical properties of elemental tungsten, including the structural, thermal, optical, electrical, and mechanical properties, as well as its preparation, production, reactivity, adsorption, electrochemical properties, and analytical aspects. This chapter also examines tungsten's metallographic properties, such as melting, powder metallurgy, singe crystals, and polycrystallinity. The third chapter reviews the properties of tungsten with other metals, metalloids, acids, and salts. This book is of value to inorganic, organic, and analytical chemists, as well as chemistry teachers and students.

This book was released on 1963 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tungsten tubes suitable for secondary fabrication have been extruded from various starting materials. Pressed and sintered sleeves, vapor-deposited tubes, and pre-extruded tubes have been successfully extruded. In addition, consolidation and extrusion of high-purity tungsten powder in a single extrusion show promise. Various starting materials are being evaluated on the basis of obtaining good fabricability and properties, as well as providing a more economical means of producing high-quality tubing.

Book excerpt: Tungsten Carbide - Processing and Applications, provides fundamental and practical information of tungsten carbide from powder processing to machining technologies for industry to explore more potential applications. Tungsten carbide has attracted great interest to both engineers and academics for the sake of its excellent properties such as hard and wear-resistance, high melting point and chemically inert. It has been applied in numerous important industries including aerospace, oil and gas, automotive, semiconductor and marine as mining and cutting tools, mould and die, wear parts, etc., which also has a promising future particularly due to enabling to resist high temperature and are extremely hard.

Available in PDF, EPUB and Kindle. Book excerpt: Tungsten heavy alloy bars 1.35 inches in diameter were prepared and evaluated for uniformity of properties. Alloys contained 97.1% to 97.3% tungsten with primary emphasis on the 97.1W-1.6Ni-0.7Fe-0.5Cu-0.1Co composition. To achieve high uniform densities with this alloy, it was necessary to use fine tungsten powder (approx 1-1.5 micrometers) and slow heating rates between 1000 C and the sintering temperature. This was not necessary with similar alloys containing no copper. Tensile elongation was found to be strongly dependent on oxygen levels in the sintered bars. Low oxygen levels gave the best results with 16-17% elongation when oxygen levels were below 6 ppm. These very low oxygen levels were only achieved with alloys containing no copper. (Author).
