Title: Irradiation creep by climb-enabled glide driven by transient point defect processes

Abstract

Irradiation creep takes place over a wide temperature range by processes fundamentally different from thermal creep. In recent work it has been shown that transients and spatial inhomogeneities in point defect fluxes are important in driving irradiation creep. Earlier theoretical work had centered on the contributions of quasi-stationary and uniform point defect concentrations to creep. In the present paper, mechanisms that depend in an essential way on these inconstancies are emphasized. Creep by climb-enabled glide driven by startup-induced, glide-induced, and cascade-induced mechanisms are explored. Calculated results are presented and compared with experimental data. 13 refs., 5 figs.
