| Abstract Scope |
Using atomistic simulation, we study the material response of the steady-state micro-structure produced under high-dosage irradiation conditions. Such a micro-structure contains an extended dislocation network embedded in a largely homogeneous population of vacancies. We find that local perturbations to such a structure can result in a non-local response, reflecting a steady-state fluctuation spectrum driven by internal stresses that accumulate the stochastic generation of point defects. Both BCC Fe and W are considered up to canonical DPA values of O(20). |
