Answer
Cold-worked metals are more susceptible to corrosion than noncold-worked metals because of the increased dislocation density for the noncold-worked metals. The region in the vicinity of a dislocation that intersects the surface is at a higher energy state, and thus, more readily attacked by a corrosive solution.
