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.

This book was released on 1966 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study has been conducted of the properties of tungsten fabricated from three ingots consolidated by electron-beam melting. The study included purity as a function of number of melts, recrystallization a d grain growth behavior, low-temperature ductility, and high-temperature tensile and creep strength. The level of most metallic impurities in tungsten decreased with increasing number of electron-beam melts, the reduction being greatest for aluminum, iron, nickel, and silicon. The levels of interstitial impurities generally were not affected by remelting. Resistivity ratios for single crystals machined from ingot slices tended to increase on remelting. The recrystallization rates for worked, electron-beam- melted (EB-melted) tungsten were significantly higher than those observed earlier for arc-melted tungsten. The grain growth rates of EB-melted tungsten were higher than those reported previously for arc-melted tungsten, further reflecting the higher purity of the EB-melted materials. The activation energies for both recrystallization and grain growth in EB-melted tungsten were consistent with expected values assuming grain boundary self-diffusion to be the rate-controlling reaction. The ductile-brittle bend transition temperature for EB-melted tungsten is slightly higher in the worked condition than that reported for arc-melted tungsten. In the recrystallized conditions, the transition temperatures for EB- and arc-melted tungsten are similar. The tensile strength of EB-melted tungsten at 2500 to 4000 F is less than that of arc-melted tungsten. This is partly associated with the large grain size of EB-melted tungsten. However, when compared at the same grain size,
