| Abstract Scope |
Current best practices for assessing stress corrosion cracking (SCC) susceptibility in Al thin gauge products utilize exposure trials of final formed product to aggressive environments, which complicates SCC assessments during alloy development efforts. Given the continuous effort in developing next-generation Al products, a need exists to develop quantitative SCC experiments conducive for thin Al sheet. This study reports the results of a test method development effort to evaluate SCC susceptibility in two aluminum alloys (AA3104 and AA5182). Static and slow-rising displacement SCC experiments are executed on thin sheet specimens immersed in 0.6 M NaCl, with SCC initiation from an induced scoring groove monitored via direct current potential difference methods. Results are employed to quantify the difference in SCC susceptibility between AA3104 and AA5182, while detailed characterization of interrupted specimens are used to identify microstructural factors responsible for differences in SCC susceptibility. |
