Paper Title:
Modeling of Structural Degradation of AlCu4Mg1 for Extruded Stringer Type Specimens Exposed to EXCO Solution Environment
  Abstract

Results are summarized of feasibility of using model for description of exfoliation corrosion (EC) in modeling of structural degradation of AlCu4Mg1 (Al2024) on extruded stringer type specimens in EXCO solution for different times of exposure. The effect of time for time development of this localized form of corrosion was assessed by using the approach of Robinson. Briefly, this approach makes possible description of intergrannular penetration observed under blisters formed by voluminous corrosion products. However, intergrannular stress supposed to be resulting from the expansion of corrosion products along dissolved grain boundaries is not taken into account in this model. Possible application of concept of intergrannular stress incorporation into EC model is discussed for modeling of structural degradation of Al2024 in EXCO tests.
