Resumo
Gamma uranium-molybdenum alloys has been considered as the fuel phase in plate
type fuel elements for MTR reactors due to its performance under irradiation and
metallurgical processing. To its usage as dispersion phase in aluminum matrix, a necessary
step is the conversion of the as cast structure into powder, and the technique considered at
IPEN / CNEN - Brazil was HDH (hydration-dehydration). This work has the aim to study the
hydrogen incorporation by gamma-UMo alloys with 8% weight molybdenum. The samples
were thermally treated under constant flow of hydrogen, for temperatures varying from 500o
C
up to 600o
C and times of 1 to 4 hours. Some of the curves relating mass incorporation and
time for the above temperatures were obtained, and the results related to its microstructures
and ease of fragmentation.
