Corrosion
Selective Corrosion (Dealloying)
Also known as: Dealloying, Selective Leaching
A mechanism in a multi-phase or multi-element alloy in which one constituent is preferentially dissolved away, leaving behind a porous, weakened that can retain the original shape of the component even though its mechanical integrity has been lost. of brass is one of the most common and well-documented examples of this mechanism.
