The effects of different amounts of stretch forming (0-12%) on the mechanical, microstructural, and corrosion properties of two third-generation Al-Cu-Li alloys (2099 and 2196) are being investigated. Of particular interest are the effects of forming contoured components with varying amounts of prestrain prior to aging on the exfoliation corrosion behavior of these alloys in service. In addition to typical characterization techniques (hardness, SEM, TEM, etc.) and corrosion tests, the samples are being examined using 2D digital image correlation (DIC) to track micro-scale deformation. Electron backscatter diffraction (EBSD) is also being performed prior to and after DIC. This work is being conducted as part of the NSF I/UCRC Center for Advanced Non-Ferrous Structural Alloys (CANFSA) and the support of NSF and the member companies is greatly appreciated.
