Abstract
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 <1 1 1> orientation (<10°) was 1.88 times higher than that of the near <0 0 1> orientation prior to annealing and 3.58 times higher after annealing. Voltammograms were performed on single grains with low index planes. The critical current density was 53% higher on <0 0 1> grains as compared to <1 1 1> grains. These results are used to discuss the electrochemical behaviour of the polycrystalline FeAlCr.
