FIGURE 9.21 Tensile behavior following exfoliation corrosion and mechanical removal of corrosion-induced surface damage for alloy 8090: (a) L direction and (b) LT direction.

fatigue crack propagation rate is depicted. Corrosion caused by the exposure in exfoliation corrosion solution for 36 h has practically no influence on fatigue crack growth behavior. Summarized in Table 9.42 are the determined constants C and n of the Paris equation:
