摘要

Abstract

We report

in situ

atomic-scale investigation of late-stage void evolution

including growth

coalescence and shrinkage

under electron irradiation. With increasing irradiation dose

the total volume of voids increased linearly

while the nucleation rate of new voids decreased slightly and the total number of voids decreased. Some voids continued to grow while others shrank to disappear

depending on the nature of their interactions with nearby self-interstitial loops. For the first time

surface diffusion of adatoms was observed to be largely responsible for the void coalescence and thickening. These findings provide fundamental understanding to help with the design and modeling of irradiation-resistant materials.
