METHODS FOR PRODUCING SODIUM/MOLYBDENUM POWDER COMPACTS

摘要

A METHOD FOR PRODUCING A METAL ARTICLE ACCORDING TO ONE EMBODIMENT MAY INCLUDE: PROVIDING A SUPPLY OF A SODIUM/MOLYBDENUM COMPOSITE METAL POWDER; COMPACTING THE SODIUM/MOLYBDENUM COMPOSITE METAL POWDER UNDER SUFFICIENT PRESSURE TO FORM A PREFORMED ARTICLE; PLACING THE PREFORMED ARTICLE IN A SEALED CONTAINER; RAISING THE TEMPERATURE OF THE SEALED CONTAINER TO A TEMPERATURE THAT IS LOWER THAN A SINTERING TEMPERATURE OF MOLYBDENUM; AND SUBJECTING THE SEALED CONTAINER TO AN ISOSTATIC PRESSURE FOR A TIME SUFFICIENT TO INCREASE THE DENSITY OF THE ARTICLE TO AT LEAST ABOUT 90% OF THEORETICAL DENSITY.
