X-Ray Tomography Analysis Correlating Pit Growth and Rolling Conditions in a High-Performance Aluminum Alloy
Aluminum alloys are commonly used for engineering applications due to their high strength to weight ratio and low cost; however, saltwater environments can shorten parts’ longevity by causing pitting corrosion. To advance the analysis of pit growth in the AA7075, this study leveraged x-ray microtomography to observe pit growth in 4D. Previous projects have correlated the growth of pits with the structure of intermetallic inclusions near the surface, and 3D models of pitted regions were produced here, with the goal of combining the resulting images with quantitative data to develop a new model for localized corrosion in AA7075.
