Abstract

Abstract Results from a series of pulsed irradiation creep tests have indicated a significant effect of beam heating on pulsed irradiation creep behavior. A pulsing effect due to intermittent atomic displacement damage was not observed. Sheet metal specimens were irradiated at 473 K using 15 MeV deuterons and a stress of 200 MPa. The pulse cycle consisted of 1000 seconds of irradiation followed by 100 seconds of annealing. Pulsed irradiation creep behavior was compared with steady irradiation creep behavior. The experimental results were interpreted using models of intermittent displacement damage and theories of temperature history effects.
