Fracture toughness of ferritic alloys irradiated in HFIR
Technical Report
·
OSTI ID:5400544
The fracture toughness of HT-9 and 9Cr-1Mo irradiated in HFIR to 10 dpa at 50/sup 0/C was evaluated using electropotential single specimen techniques. Circular compact tension specimens were tested at temperatures ranging from room temperature to 450/sup 0/C. The test results were analyzed using the J-integral approach. Analyses showed that the fracture toughness of both alloys was reduced as a result of HFIR irradiation. The degradation of irradiation toughness resistance was more severe for 9Cr-1Mo than HT-9. The thickness criterion for valid J/sub 1c/ values was satisfied by the thickness of the test specimens.
