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 ...

摘要:Abstract(#br)The evolution of fission gas bubbles in irradiated materials plays a critical role in the microstructural processes that leads to dimensional changes of U-Mo alloy fuels, e.g., fuel swelling. Although the intergranular bubbles-induced fuel swelling has been long-disc...

摘要:Abstract(#br)U-Mo alloys are promising fuels for future high-performance research reactors with low enriched uranium. Surface properties, such as surface energy, are important inputs for mesoscale simulations (e.g., phase field method) of fission gas bubble behaviors in irra...

摘要:Abstract(#br)A mesoscale model is developed by integrating the rate theory and phase-field models and is used to study the fission-induced recrystallization in U-7Mo alloy. The rate theory model is used to predict the dislocation density and the recrystallization nuclei density d...

摘要:Abstract(#br)The microstructure evolutions of FePt-X (segregant) thin films were studied by employing a three-dimensional phase field model. Simulated results show that in the absence of substrate constraint related with elastic energy, the morphology of the FePt-X thin films sig...

摘要:Abstract(#br)We present a possible physical origin underlying the relationship between temperature and hydrogen (H) blistering nucleation/dissociation in metals according to systematic first-principles calculations in junction with statistical model and diffusion theory employing...

摘要:Abstract(#br)Grain size is an important factor in controlling the swelling behavior in irradiated U–Mo dispersion fuels. Increasing the grain size in U–Mo fuel particles by heat treatment is believed to delay the fuel swelling at high fission density. In this work, a multisc...
