DUCTILITY OF REFRACTORY METALS THROUGH THERMAL TECHNIQUES,
Abstract
Commercially pure sintered and wrought tungsten and molybdenum wires, 0.030-inch in diameter, were used for this investigation. Considerable experimentation with the tungsten wires in an effort to achieve some measure of room-temperature ductility proved futile. These experiments were temporarily abandoned in favor of the studies on molybdenum. Molybdenum wires were heated to selected elevated temperatures in a vacuum of approximately 2 x 0.00001 torr in less than 1 minute, held at temperature for 20 minutes, and vacuum cooled to determine the temperature at which maximum ductility occurs on rapid heating. The results obtained led to the assumption that there is a certain temperature, or temperature range, below which molybdenum is ductile, regardless of heating rate or time at temperature, within reasonable limits.
