摘要：

The pre- and postirradiation notch toughness of austenitic stainless steel plates and weld deposits was explored to aid materials selection and application for liquid metal fast breeder (LMFBR) reactors. The study encompassed six plates (AISI Types 304, 316, 304L, 316L), two submerged arc weld deposits (Types 308 and 316), and one shielded metal-arc weld deposit (Type 308). Dynamic tear (DT) and Charpy-V test methods were employed to determine notch toughness trends. Results show that types 304 and 316 weldments show significant reductions in dynamic tear and Charpy-V notch ductility with elevated temperature irradiation to intermediate neutron fluence in the EBR-II reactor.
