The effect of sub-eutectoid heat treatment on the phase transformation behavior in rolled U-10 wt.% Mo (U10Mo) foils has been systematically investigated. Three starting microstructures have been evaluated: (i) as-rolled condition, (ii) as-rolled + annealed at 700°C for 1 hour, and (iii) as-rolled + annealed at 1000°C for 60 hours. Annealing at 700°C resulted in small grain size (15 ± 9 µm average grain size), while annealing at 1000°C leads to very large grains (156 ± 118 µm average grain size) in rolled U10Mo foils. Later the samples were subjected to sub-eutectoid heat-treatment temperatures of 550°C, 500°C, and 400°C for different durations of time starting from 1 hour up to 100 hours. U10Mo rolled foils went through various degrees of decomposition and formed a lamellar microstructure through a cellular reaction. The least amount of cellular reaction was observed in the large-grain microstructure at all temperatures.
