Title: Hydrogen transport in nickel base stainless alloys

Abstract

Hydrogen transport parameters have been measured in HASTELLOY Alloys C-276 and over the temperature range of 17 to 90/degree/C. The two alloys exhibited dramatically different hydrogen behavior. For Alloy C-276, diffusivity in both the cold worked and annealed conditions decreased by a factor of two following low temperature (500/degree/C) aging. Hydrogen trapping was not observed. An analysis of hydrogen transport in Alloy G indicated reversible and irreversible trapping by niobium substitutional atoms and second phase carbides, respectively. The results are related to hydrogen embrittlement tendencies. 37 refs.
