ABSTRACTGrain boundary chemistry in an X750 Ni alloy was analyzed by atom probe tomography in an effort to clarify the possible roles of elemental segregation and carbide presence on the stress corrosion cracking behavior of Ni alloys. Two types of cracks are observed: straight cracks along twin boundaries and wavy cracks at general boundaries. It was found that carbides (M23C6 and TiC) are present at both twin and general boundaries, with comparable B and P segregation for all types of grain boundaries. Twin boundaries intercept γ’ precipitates while the general boundaries wave around the γ’ and carbide precipitates. Near a crack tip, oxidation takes place on the periphery of carbide precipitate.

Abstract The stress corrosion cracking (SCC) of 90/10 Cu-Ni alloy in sulfide solutions is not reported in the literature. The SCC behavior of the alloy was studied in dilute and concentrated Na2S solutions at room temperature. The alloy was found to be susceptible to SCC under slow strain rate conditions in the concentrated (0.1 to 1 M) sulfide solutions, but not in the dilute (0.002 to 0.03 M) solutions. On the basis of electrochemical data and EPMA analysis of the metal/film interface of the cracked samples, the mechanism of cracking can possibly be attributed to a dealloying (selective dissolution) phenomenon where the copper matrix but not the solute Ni is selectively removed.
