THE FLOW AND FRACTURE OF ZONE REFINED TUNGSTEN

Abstract

Zone-refining efforts were directed toward enhancing the control of the zone. These efforts included additional coil designs, effect of atmosphere gas velocities, and zone-refining while power fluctuations were at a minimum. Resistivity ratios were determined on two as-received electron-beam zone-refined single crystals of tungsten. A description of the measuring apparatus and the values obtained are presented. A technique for measuring resistivities by an eddy-current method is described briefly.
