Phase transformation kinetics has been investigated in a cast and homogenized U-10wt%Mo alloy through isothermal heat-treatment studies carried out at 500° C and 400° C. The cast and homogenized alloy fully consisted of metastable bcc γ-UMo phase. Isothermal heat-treatment led to formation of a lamellar microstructure along the grain boundaries of initial γ-UMo phase. At 500° C, 1.4 % transformation was observed after one hour of thermal exposure, and almost complete transformation of the initial γ-UMo phase was noted after 100 hours of thermal treatment. At 400° C, only 5.1 % of the initial γ-UMo phase transformation has been noted after 100 hours of exposure. The lamellar microstructure formed at 400° C is significantly finer compared to 500° C condition. However, after 10 days and 21 days of exposure at 400° C, a very different looking microstructure forms. Results of these heat-treatment studies will be reported here.
