Computer simulation of a thermal annealing in metals at defects irradiation by high-energy ions

The computer model describing the migration and interaction of defects stayed on a Surface of a metal after the irradiation by high-energy ions is offered. In the past, defect accumulation under irradiation has been mainly treated within the framework of a mean field chemical-rate theory approach ill which both vacancies and self-interstitial atoms (SIA) are assumed to be produced as monodefects and clusters of both types of defects to be immobile. This picture may be too simple to describe the defect kinetics under cascade damage condition where a variety of defect Clusters characterized by different properties are continuously being generated. Ail alternative way is the computer modelling by the Monte Carlo method allowing to investigate the point defects and their complexes in details. In a given paper, diffusion Of Clusters is taken into account completely, and the role of one-dimensional gliding of SIA's Clusters is studied that allows to check up more completely the regularities influencing oil migration and interaction between radiation damages.
