SOME OBSERVATIONS ON URANIUM-RICH URANIUM RUTHENIUM ALLOYS

Technical Report ·
OSTI ID:4335072

The solidus and liquidus depressions in U-rich U--Ru alloys are approximately 5 and 1 deg C for 0.1 at.% Ru addition, respectively. A eutectic occurs at 900 deg C and 18 at.% Ru between U and an intermetallic compound of unknown compesition. The alpha yields beta and beta yields gamma transformation temperatures in U are lowered by additions of Ru, but in alloys containing up to 20 at.% Ru sharp arrests can be detected at heating and cooling rates of 11/2 deg C/min. The solubility of Ru in gamma uranium is approximately 10 at.% at 900 deg C, the solability in alpha uranium being considerably lower. (auth)
