Abstract
Electrowon tungsten powders were investigated with respect to consolidation, fabrication, and mechanical properties. Sheet, 0.03- Inch thick, was produced and its tensile strength measured between 250 deg. and 1,935 deg. C. The large particle size of electrowon tungsten effectively precluded sintering to a density sufficient to allow hot working to sheet or bar. The powders were consolidated by die pressing to 70-percent density, sheathing in molybdenum, and high-energy-rate extruding to either round or sheet bar of 100- percent density. The material was then rolled conventionally to sheet. The mechanical properties of the sheet prepared from the electrowon powders compared favorably with those reported in the literature for sheet prepared from commercially produced hydrogen- reduced powder.
