Abstract:
Zone-refined crystals of both thermally and electrolytically reduced beryllium were converted to polycrystalline aggregates by a combination of deformation and heat treatment. The resulting polycrystalline aggregates were subjected to deformation at 450 C by standard beryllium wiredrawing techniques. A limited amount of metallurgical evaluation of the resulting wire was accomplished. It was found that combination of twinning and primary recrystallization was required to convert the single crystal to a truly polycrystalline aggregate. The wire produced from zone-refined beryllium exhibited usable structural tensile-properties at room temperature.
