Presentation Title Directional Sensitization Responses in 5XXX Series Aluminum Alloy Microstructures
Author(s) Likun Sun, Matthew A. Steiner
On-Site Speaker (Planned) Likun Sun
Abstract Scope The extent of intergranular corrosion in sensitized 5XXX series aluminum alloy plates is highly dependent on the exact geometric configuration of networked high-angle grain boundaries available for propagation normal to the exposed surface. Utilizing adaptations of the Nitric Acid Mass Loss Test (NAMLT) standard commonly used to assess bulk sensitization in these alloys, we will present the isolated directional intergranular corrosion responses from different rolled plate microstructures as a function of their time-temperature history. We will show how both the magnitude and kinetics of the directional sensitization responses exhibited by these microstructures contributes to variations in the bulk measurements of nominally identical 5XXX series aluminum alloy plates, despite their shared alloy-temper designation. Lastly, we will highlight how the directional sensitization responses correlate with features of the grain boundary configurations in ways that render the microstructural data predictive of the intergranular corrosion behavior, with direct implications to stress corrosion cracking.
