Peak bare-surface current densities based on the scratched electrode test are seriously in error and repasivation rates grossly overestimated. Influences of potential and pH on reactions of bare surfaces are better understood. Correlation between charge transfer and corrosion fatigue crack growth response was established for Fe18Cr12Ni alloy in deaerated 0.6N NaCl at RT. Strong correlation was established between morphology of corrosion fatigue fracture surfaces and cracking in hydrogen charged samples. Attempts at growing bicrystals by strain annealing were not successful.
