| Abstract Scope |
Helium accumulation in metals via nuclear transmutation or direct injection can greatly alter the properties of materials in extreme environments. Metallic and ceramic materials can be designed to accommodate He inclusion, yet the thermal and mechanical properties must respond in predictable ways. However, coupled extreme environments alter the dynamics of He bubbles in materials. Through in-situ and real-time analysis, one can probe the transients of material evolution and inform longer-scale investigations and computational modelling efforts. To explore He effects, this work will show the heating rate impact on He bubble sizes, 3D reconstruct He bubbles at interfaces, decipher near-bubble composition impacts on bubble motion, and compare human and artificial intelligence analyzing He bubbles, all with a focus on bubbles in refractory alloys. Finally, we will discuss the effect of coupled environmental stimuli that He-producing environments, such as nuclear fusion reactors, will contain and experimental techniques to probe said coupled environments. |
