Fracture toughness of structural material for LHD
- 1. National Inst. for Fusion Science, Toki, Gifu (Japan)
Description
Several fracture toughness tests have been carried out to characterize and confirm a structural reliability of Large Helical Device. A material used for a supporting structure of helical and poloidal coils is an austenitic stainless steel (SUS316). This material has a yield stress of over 620 MPa and a fracture toughness of over 300 MPa√m at 4.2 K. In this paper, an effect of a magnetic field on the toughness, the toughness of a weld joint which has a natural crack at weld root, and the toughness of a full size thickness specimen will be summarized.
