Segregation of S and Sb to the internal free surfaces of creep induced cavities and microcracks in Ni and an Fe + 15% Ni + 15% Cr alloy have been studied using scanning Auger electron spectroscopy (AES). Residual S is found to segregate strongly in the undoped Fe + 15% Ni + 15% Cr while Fe + 15% Ni + 15% Cr + 1% Sb exhibited only Sb segregation. Both S and Sb segregated in Ni + 0.15% Sb.
