Progress was achieved in the development of methods for the extrusion and drawing of tungsten tubing. Fabrication and properties of the drawn and extruded tungsten tubes are outlined. The effects of iron and silicon additions on the mechanical properties of zone-refined beryllium crystals are evaluated. The most significant conclusion is that iron at about the 1000 ppm level in the absence of other impurities is beneficial to deformation behavior. There appears to be some sacrifice in ductility at the 100 ppm iron level. Silicon up to 350 ppm in the absence of iron appears to have little effect on deformation behavior other than basal work hardening. Compression tests on beryllium are reported and the results show slip, twinning, and fracture. Fabrication of splat- cooled copper-uraniun and berylliumuraniun alloys for metallographic examination and mechanical testing is discussed. (N.W.R.)
