- Title
Efficiency of dislocations as sinks of radiation defects in fcc copper crystal.
- Authors
Sivak, A.; Sivak, P.
- Abstract
The sink efficiency of perfect dislocations for self-point defects (interstitials and vacancies) in fcc copper crystal has been calculated by the kinetic Monte Carlo method in a temperature range of 293-1000 K and a range of dislocation densities from 1.3 × 10 to 3.0 × 10 m. Screw, mixed, and edge dislocations with a Burgers vector 1/2<110> in different slip systems are analyzed. The interaction energies of self-point defects with dislocations are calculated using the anisotropic theory of elasticity. Analytical expressions are proposed for the dependences of the calculated values of dislocation sink efficiency on temperature and dislocation density.
