説明

Stress-controlled fatigue tests were performed for 20% cold-worked 316 stainless steel under in-situ 10 MeV deuteron irradiation with an energy degrader at 60 and 300°C. The irradiation dose rate and the deuterium implantation rate were arranged in response to beam intensity in three conditions as (A) 1.0×10−7 dpa/s and 1.1×10−3 appm/s, (B) 5.0×10−7 dpa/s and 5.5×10−3 appm/s and (C) 1.0×10−6 dpa/s and 1.1×10−2 appm/s, respectively. The number of fatigue cycles to fracture (NF) increased with the dose rate in order of conditions (A), (B) and (C) at 300°C, while NF was lower in condition (C) than that in condition (B) irrespective of the higher dose rate at 60°C. Although transgranular cracking in the ductile fracture mode was indicated on fracture surface for all specimens, higher density of dimples was formed for the in-situ irradiation specimen in condition (C) at 60°C. Some evidence of effects of implanted deuterium on in-situ irradiation fatigue behavior were demonstrated in this paper.
