FUNDAMENTAL AND APPLIED RESEARCH AND DEVELOPMENT IN METALLURGY. Progress Report to United States Atomic Energy Commission, April 1962
Activities in an investigation of refractory metal alloys aimed at relating their high-temperature properties to features of their phase diagrams, microstructures, and thermal histories are reported. Selected compositions from binary systems containing Hf, Os, Re, and Ru are being investigated. During the report period, ingots of unalloyed Nb, unalloyed Ta, Mo-10 at.% Hf, and W-5 at. % Ru were prepared and extruded. A summary of extrusion data is included. The unalloyed Nb and Ta extruded at 1850 deg , and extrusions of Mo-10 at.% Hf were successful at 2000 deg . Extrusions of the W-5 at.% Ru failed to produce material for mechanical testing. The extruded refractory materials were evaluated by tensile tests at 1200, 1400, and 1600 deg C and hot hardness measurements at 300, 500, and 800 deg C. (J.R.D.)
