Abstract This paper presents the results of a study on the effects of water, acetic acid (CH3COOH), oxygen, corrosion inhibitor, chloride, methanol (CH3OH), denaturant, and corrosion product on the stress corrosion cracking (SCC) of steel in ethanol (C2H5OH). The factor that was found to have the greatest effect on causing SCC was corrosion potential, as influenced by oxygen. The lower critical potential for SCC ranges from 25 mV vs. saturated calomel electrode (SCE) to 300 mVSCE, depending on the presence of chloride and methanol as impurities. Galvanic contact with precorroded steel appeared to exacerbate SCC by increasing the corrosion potential. Within the fuel ethanol specification limits, chloride had a less significant effect than oxygen. SCC was intergranular when the chloride concentration in ethanol (both laboratory and field samples) was low (less than 1 ppm) and it was transgranular when the chloride concentration was high (32 mg/L). A denaturant, a corrosion inhibitor, and acidity, within the...

Abstract Polarization and Mott-Schottky experiments were performed on alloy 625 samples previously exposed to 1.2 MeV gamma radiation at dose rates up to 1 Mrad/hour. While the breakdown potential is dependent on dose rate, the repassivation potential is not. These residual effects of the radiation exposure were not observed on samples exposed to the field in an air environment. At the highest dose rate, trapped holes at the surface at potentials above the repassivation potential result in a significant reduction in the crevice corrosion nucleation time.
