RECOVERY AND RECRYSTALLIZATION OF U$sub 3$Si.
Technical Report
·
OSTI ID:4756466
The recovery and recrystallization temperatures of U{sub3}Si were determined for an alloy of uranium-3.98 wt% silicon containing 600 ppm carbon. Small specimens, deformed by compression, were isothermally and isochronally annealed at temperatures between 350 and 700 degC and their recovery and recrystallization temperatures determined using hardness, grain size and x-ray measurements. For small amounts of strain and an annealing time of 6 hours both recovery and recrystallization is achieved at 650-700 degC. The effect of small changes in silcon and carbon concentration were determined by examining two further alloys containing 3.27 wt% silicon and 600 ppm carbon, and 4.02 wt% silicon and 140 ppm carbon respectively. A small change in silicon concentration does not affect recovery and recrystallization but decreasing the carbon concentration from 600 to 140 ppm decreases the recovery and recrystallization temperatures.
