Dealloying is a common corrosion process during which an alloy is "parted" by
the selective dissolution of the electrochemically more active elements. This process
results in the formation of a nanoporous sponge composed almost entirely of the
more noble alloy constituents1
. Even though this morphology evolution problem has
attracted considerable attention, the physics responsible for porosity evolution have
