Polycrystalline Fe7.5Al7Cr is a ferritic light weight steel that shows a strong anisotropic dissolution behaviour. This electrochemical phenomenon was investigated by use of a scanning droplet cell (SDC). The crystallographic orientation of the single grains was determined by electron back scatter diffraction (EBSD). The fraction of grains with a near (111) orientation (<10 degrees) was 1.88 times higher than that of the near (001) orientation prior to annealing and 3.58 times higher after annealing. Voltammograrns were performed on single grains with low index planes. The critical current density was 53% higher on (001) grains as compared to (111) grains. These results are used to discuss the electrochemical behaviour of the polycrystalline FeAlCr. (C) 2005 Elsevier Ltd. All rights reserved.
