1. Atom scale structure and minor solute exert strong effects on the corrosion properties of ideal solid solution alloys The effects of structural (order–disorder transformation, glass relaxation), chemical (solute clusters, minor solute elements) and structural + chemical defects (solute rich and lean nanocrystals in an amorphous solid solution) on corrosion are investigated using model alloys. Disordered crystalline Fe 50 Pd 50 : The disordered structure has strong grain orientation dependent dissolution [1] even after large amounts of dissolution [2]. Dissolution behavior is dominated by the dissolution of irrational orientations producing high surface roughness caused by significant faceting to low index planes. - The formed terrace-ledge structure was maintained in individual grains after increased dissolution. These observations are consistent with dissolution eventually revealing slow dissolving low index terraces and steps. Further dissolution proceeds most rapidly laterally on the ledge and kink facets.

2. Corrosion Education 6 high school students (M. Fox, S. Gorsch, L. Scully, D. Harrington, S. Gorsch, A. Clyman), 3 Undergraduates (H. Bindig, W. McCarthy, A. Nguyen), 3 graduate students (T. Aburada, N. Tailleart D. Horton), and 2 post-doctoral researchers (H. Ha, D. Horton) contributed to this NSF- supported project. Graduate & undergraduate courses in corrosion taught both in class and via distance learning (both MSE 7080 and MSE 3080) for Produced-in-Virginia for Engineers that bring engineering education to workers. John R. Scully served on National Academy Study on Research Opportunities In Corrosion (ROCSE). (Fall 2010). Corrosion Video distributed Corrosion Education 6 high school students (M. Fox, S.
