Recrystallization kinetics of cold-rolled U-10 wt% Mo

Samples of U-10 wt%Mo (Usbnd Mo) alloy were thermomechanically processed and annealed at 600 °C and 700 °C for periods lasting up to 8 h. Annealed microstructures were examined using electron backscattered diffraction in order to estimate the completeness of recrystallization. Hardness measurements of the Usbnd Mo samples were taken to further qualify the progress of recovery and recrystallization. This allowed us to evaluate the recrystallization activation energy and the recrystallization kinetics with a Johnson-Mehl-Avrami-Kolmogorov equation. The results show that the activation energy of recrystallization is approximately 100.6 ± 23.1 kJ/mol. The mechanisms active in the recrystallization of cold-rolled U-10 wt% Mo are discussed in the context of these results.
