Grossbeck, M L; Liu, K C

Nimonic PE-16 was irradiated in the HFIR to 6 to 9 dpa and 560 to 1000 at. ppM He at 430/sup 0/C. Postirradiation fatigue tests revealed a reduction in fatigue life by about a factor of 10 at 430/sup 0/C. In contrast to AISI type 316 stainless steel, no endurance limit was observed. All irradiated specimens exhibited some intergranular fracture with an increasing tendency toward cleavage-like intragranular fracture for low strain ranges.
