摘要:Abstract(#br)The radiation-induced amorphization of U 3 Si 2 was investigated by in-situ transmission electron microscopy using 1 MeV Kr ion irradiation. Both arc-melted and sintered U 3 Si 2 specimens were irradiated at room temperature to confirm the similarity in their re...

摘要:Abstract(#br)We have developed a mesoscale phase-field model for studying the effect of recrystallization on gas-bubble-driven swelling in irradiated U-Mo alloy fuel. The model can simulate the microstructural evolution of the intergranular gas bubbles on the grain boundaries as ...
