REDUCTION AND CONSOLIDATION OF SUPERIOR QUALITY MOLYBDENUM ALLOYS

Abstract

Two arc melted and one electron-beam melted extrusion billets of calcium reduced Mo were extruded to sheet bars. These extrusions were processed into sheet and evaluated. The electron-beam melted Mo had a recrystallization temperature of 1500 F for one hour compared to 2600 F for the arc melted material. Mechanical properties of the two materials tested were comparable to commercial arc melted molybdenum. Heat treatment studies on hydrogen reduced electron-beam melted Mo showed the material to be brittle after complete recrystallization.
