Mathematical modeling of radiation processes in constructional materials in ion irradiation

Abstract

Processes of radiation formation of defects in the iron exposed to radiation by various ions are considered in the work. Issues of application of iron and alloys on the basis of iron in the industry are searched. The algorithm is developed for calculation of cascadely - probabilistic functions (CPF), concentration of radiation defects, computations are led, the regularities arising at calculations of cascadely - probabilistic functions depending on initial energy of a primary particle, atomic number of a flying particle, depth of penetration. Also calculations of concentration of radiating defects are executed at an ionic irradiation in iron. Areas of finding of result for CPF, calculated depending on number of interactions and depth of penetration, concentration of cascade areas are received. It is matched approximated expression and coefficients of approximation for various flying particles in iron are found. Results of calculations are presented in the form of tables and schedules.
