Abstract
Effects of coherent and incoherent precipitates on point defect concentrations, recombination rate, and growth of vacancy voids in irradiated materials were considered. A new mechanism of defect loss by enhanced recombination inside coherent precipitates was described. Vacancy swelling suppression, based on the recombination mechanism of point defect loss to coherent precipitates, was shown to be efficient in a wide range of irradiation conditions - from heavy ion irradiation to in-reactor irradiation. Point defect fluxes arising in the vicinity of the coherent precipitate due to difference between recombination rates in the precipitate and matrix, results in segregation fluxes of alloying elements. This effect, being an analog of the inverse Kirkendall effect, influences stability of the coherent precipitates. Modification of chemical composition of coherent precipitates - phenomenon observed experimentally - is likely to be caused by the recombination-driven segregation, followed by infiltration of segregating elements into the precipitates. 39 refs.; 7 figs.; 1 table.
