Computational Models of Individual Differences in Working Memory Capacity.

摘要

This report summarizes a 3-year program focused on the localized corrosion of Al and Al alloys. The primary objective of this project is to understand the kinetics of localized corrosion in Al alloys. The first part of this work used the thin film pitting technique to address pit kinetics. The second part of the work used the foil penetration technique to provide quantitative measurements of the rate of localized corrosion propagation in real alloys. This work has focused on intergranular corrosion (IGC) because the attack in Al alloys seems to transition into IGC as it grows. A statistical model to describe the effect of microstructure on the IG path length and thus penetration rate was developed. The third part of the work probed the ICC susceptibility of 7xxx series Al alloys by quantitative TEM analysis of the composition of grain boundary intermetallic phases and electrochemical studies of bulk and thin film analogs of these regions. A model describing the effect of temper on ICC of 7xxx alloys was developed.
