Grain Boundary Anisotropy and Its Influence on Helium Bubble Nucleation, Growth, and Decohesion in Polycrystalline Iron
Yang Zhang, Peter Hatton, Blas P. Uberuaga +1
The accumulation of helium bubbles at grain boundaries (GBs) critically degrades the mechanical integrity of structural materials in nuclear reactors. While GBs act as sinks for ra…
