Abstract:
In the model of radiation-induced segregation, based on the first and second Fick's laws and with inverse Kirkendall effect considered, the concentration profiles of the components of the concentrated Fe–Cr–Ni alloy and radiation point defects are obtained at different temperatures, dislocation densities, dose rates. The concentration profiles were calculated from the start of irradiation to the steady state. The sensitivity of concentrations of alloy components near the surface is analyzed as function of input parameters (vacancies migration energy for Cr, Ni, Fe, interstitial migration energy, etc.).
Keywords:
radiation-induced segregation, concentrated metal alloys, concentration profiles, point defects, computer simulation.
