PROPERTIES OF YTTRIUM AND THE RARE EARTH METALS, EFFECT OF MINOR ADDITIONS TO NIOBIUM-BASE ALLOY ON ELEVATED TEMPERATURE OXIDATION RESISTANCE

Technical Report ·
OSTI ID:4747691
Approximately 180 compositions in 19 Nb based alloy types were prepared for study. Atmospheric corrosion tests were completed for 9 series of alloys. Improved corrosion resistance is indicated for a Nb alloy contain Ti, 20% W, and 3% Mo when rare earth metals are added. Possible improvement, on the addition of rare earths, is also suggested for a Nb alloy containing 11.3% Ti and 7.9% Mo. Metallurgical investigations of two alloy series failed to indicate correlation between metal interface movement or microhardness values with corrosion resistance as established by weight gain measurements.
