POWDER OF ALLOY BASED ON URANIUM AND MOLYBDENUM IN (-METASTABLE PHASE, COMPOSITION OF POWDERS COMPRISING SAID POWDER, AND USES OF SAID POWDER AND COMPOSITION Russian patent published in 2016 - IPC B22F1/02 C22C43/00 G21C3/60 

FIELD: metallurgy.

SUBSTANCE: invention relates to powder of an alloy containing uranium and molybdenum in a metastable γ-phase, powder composition containing said powder, as well as to versions of use of said alloy powder and said powder composition for making fuel elements, in particular, fuel elements for experimental nuclear reactors, and targets, intended for production of radioactive elements, in particular for imaging in medicine. Powder of an alloy is formed by particles consisting of a core of uranium-based alloy, containing molybdenum in metastable γ-phase, which is coated with a layer of aluminium oxide, which is in contact with core. Powder composition for making fuel element or target for producing a radioactive element includes uranium-based alloy powder, containing molybdenum in metastable γ-phase mixed with powder containing aluminium, wherein uranium-based alloy powder containing molybdenum, is 65-90 wt% of weight of powder composition, and powder containing aluminium, has weight content of aluminium equal to at least 80 %.

EFFECT: higher resistance of composition to action of neutron radiation.
