Fig. 7: Sample morphologies before and after thermal shock tests.
From: Transient behavior of oxide fuels with controlled microstructure and Cr2O3 additive
Before thermal shock tests: a pure-7.8 μm, b doped-10.4 μm, c doped-nano, and d pure-nano; and after thermal shock tests: e pure-7.8 μm, f doped-10.4 μm, g doped-nano, and h pure-nano (the scale bar at the bottom of the sample is 1 mm per grid).
