Some Studies on the Uranium-Molybdenum Alloy

THE EFFECT OF QUENCHING RATE ON THE TEMPERATURE AND STRAIN-RATE SENSITIVITY OF URANIUM 2w/o MOLYBDENUM ALLOY

The mechanical properties of a U2w/oMo alloy in the Y-quenched, fastgas-cooled and as-extruded states a r e compared at tensile strain rates from 10-4 to ~ 2 0 0 0 / s . Significantly higher s t ress levels a r e observed in the Y-quenched specimens at all strain ra tes and failure processes a r e studied by optical and scanning electron microscopy.

Environmental analysis of paleoceanographic systems based on molybdenum–uranium covariation

Preparation of ingots of uranium-niobium alloy

A study was made of the preparation of a uranium 10 w/o niobium alloy by the bomb reduction of a suitable form of niobium and uranium tetrafluoride with calcium. A compound with a probable formula of Na2NbOF5 proved to be most satisfactory as the source of niobium. High yields and good metal-slag separations were obtained. Chemical analysis and density determinations showed the composition to b...

Recent studies of the copper-molybdenum antagonism.

The biological antagonism between copper and molybdenum was discovered when cattle grazing pastures high in Mo were found to develop a syndrome characterized by diarrhoea, growth retardation, anaemia and achromotrichia, which could be prevented by administering Cu. This syndrome was subsequently reproduced in non-ruminants, but further studies revealed important differences in the nature of the...
