RESEARCH AND DEVELOPMENT ON NEW PROCESSES OF PRODUCING DUCTILE MOLYBDENUM
Abstract
Eleven arc-cast molybdenum heats have been pre pared in pursuance of the general objective of obtaining molybdenum with a low transition temperature. Deoxidation with carbon, titanium, and thorium has been investigated. One carbon deoxidized, unalloyed molybdenum heat has been converted to bar stock, and the impact transition temperature has been determined. Small ad ditions of chromium, nickel, and aluminum have been made to arc-cast molybdenum for the purpose of studying the solid-solution softening phenomenon. Two button melts produced by the Bureau of Mines installation at Albany, Oregon, have been examined. On the basis of hardness measurements and chemical analyses, the purity of the molybdenum buttons was not significantly different from that of commercially-available vacuum-arc-cast molybdenum.
