| Abstract Scope |
Aluminum alloys are widely used in aircraft and marine structures. While the corrosion behavior of these materials has been studied in detail, the cyclic freeze-thaw behavior has not really been examined. In this presentation, I will talk about the mechanisms for accelerated corrosion and microstructural evolution under cyclic-freeze-thaw. These will be compared to the behavior of the alloy under corrosion under continuous immersion in a salt water solution. In situ freeze-and-thaw experiments were carried out using a lab-scale x-ray microtomography system. This setup allowed us to observe and analyze the degradation, particularly the spalling of corrosion products during freezing. Novel insights into crack propagation and mechanisms of degradation under cyclic thermal conditions will be discussed. |
