LOTION 3. Dynamic fracture toughness tests of AISI 316L, TIG and electron beam weld specimens irradiated at 315K. Final report PSM 2-2

摘要

In he framework of the CEC-DGXII-Fusion NET Technology Programme, AISI 316L base material and TIG metal deposit and electron beam specimens have been irradiated at a temperature of about 350K, up to 5 dpa. Instrumented Charpy tests have been performed on irradiated and unirradiated specimens at room temperature.The fracture toughness has been calculated and irradiation hardening is observed. The TIG metal deposit and the electron beam weld show lower fracture toughness values. (Atomindex citation 27:043065)
