Abstract EN
This work focuses on a mathematical modeling of the response to irradiation of a multilayer composite material.
Nonstationary balance equations are utilized to account for production, recombination, transport, and annihilation, or removal, of vacancies and interstitials at interfaces.
Although the model developed has general validity, Cu/Nb multilayers are used as case study.
Layer thickness, temperature, radiation intensity, and surface recombination coefficients were varied systematically to investigate their effect on point defect annihilation processes at interfaces.
It is shown that point defect annihilation at interfaces mostly depends on point defect diffusion.
The ability of interfaces to remove point defects can be described by a simple map constructed using only two dimensionless parameters, which provides a general tool to estimate the efficiency of vacancy and interstitial removal in multilayer composite materials.
