Vacancy swelling of chromium

Abstract

Basic differential equations, which describe kinetics of accumulation of vacancies and vacancy porosity in materials, irradiated by streams of rapid particles in nuclear reactors or accelerating, are considered. Phenomenologiical correlations are derived for the calculation of temperature dependences of the vakansy swelling of materials in wide area of temperatures and doses of irradiation. The results of similar calculations are presented for the littlealloyed chromium irradiated in accelerating by the ions of Cr³⁺ and are compared with experimental data.
