STUDIES OF MOLYBDENUM-, TUNGSTEN-, AND CHROMIUM-BASE ALLOYS WITH IMPROVED DUCTILITY

OSTI ID:4131994
A study was conducted on rhenium-free alloys of molybdenum, tungsten. and chromium to duplicate the beneficial effect of rhenium on properties of these alloys. Twinning and reduction of interstitial solubilities were promoted by platinum-metal additions, while osmium, tantalum, and columbium changed the nature of the intergranular oxides. Improvements in the fabricability of cast molybdenum were promoted by platinum-metal additions, particularly by osmium. These additions strengthened molybdenunn but also increased the ductile-to- brittle bend transition temperature. (auth)
