Fig. 2: Phase-field predictions following a 500-h simulation for 20 μm average grain size microstructure with 5, 6, and 7 GBs present at the exposed surface compared to experimental measurements44.

Phase-field predictions for a weight loss and b corrosion depth. The data presented for each case are taken from an average of ten microstructures where the shaded colored regions represents the SD of the ten simulations.
