The addition of 0.06 monolayers of antimony to the grain boundaries of iron with 0.3 monolayers of sulfur was found to have no effect on the fracture toughness or subcritical crack growth behavior at cathodic potentials. Tests were conducted using compact tension type samples tested in 1N H/sub 2/SO/sub 4/ at cathodic potentials of -0.6V (SCE) to -1.25V (SCE). The absence of any effect of antimony on the fracture toughness was related to iron being in a minimum fracture toughness condition such that further segregation of an embrittling element had no effect. Also, the subcritical intergranular crack growth threshold was found to decrease with increasing cathodic potential consistent with results reported by others for transgranular fracture of steels in gaseous hydrogen.
