Abstract

A series of six 316LN-type alloys with different carbon contents were evaluated for suitability as conduit-sheath materials for the Nb3Sn superconductors that will be used in high-field magnets. Impact energies (at 76 to 295 K) and tensile strengths (at 4, 76, and 295 K) of annealed and “sensitized” alloys were compared. Embrittlement by aging at 700°C for 100 h (the Nb3Sn reaction conditions) was determined to be a function of carbon content; alloys with very low carbon content retained adequate toughness.
