RESEARCH AND DEVELOPMENT ON NEW PROCESSES OF PRODUCING DUCTILE MOLYBDENUM
Abstract
An investigation was made to determine the practical limits of solid- state purification of unalloyed molybdenum. It was found that by using low- pressure, flowing atmospheres of tank oxygen for decarburization and palladium- diffused hydrogen for deoxidation, that (1) the carbon content was reduced to 0. 003% from 0.019% by weight, (2) minor phases were eliminated from the microstructure, as judged by observations at X2000, (3) the room-temperature hardness was lowered to 158.5 DPH from 168.1 DPH (30 kg load), and (4) the 120 degree-bend transition temperature was raised slightly, from 365 F up to 390 F.
