The corrosion depth, d,increases with misorientation angle, θ, except near some coincidence-site-lattice boundarieswhere minimum cusps appear. For small-angle boundaries, d depends on θ following aRead-Shockley type relationship. The atomistic structure and the local expansion of grainboundaries were calculated using a computer simulation method. The structure dependence ofgrain boundary corrosion is explained in terms of variation in free volume.
