Relationships of Irradiation Creep to Swelling Implicit in the Theories of These Processes

摘要

Theoretical relationships are derived expressing irradiation creep in terms of swelling, for creep by dislocation climb, by climb-enabled glide resulting from cumulative net point-defect absorption, and by climb-enabled glide resulting from cascade-induced dislocation climb excursions. In general the creep-rate-to-swelling-rate ratio is sensitive to sink densities even for a given swelling level. Implications are seen for translation from one irradiation environment to another.
