Pattern formation during dealloying

Dealloying is a process during which an element is selectively dissolved from an alloy. If the starting material is single phase and within certain compositional limits dealloying results in the formation of bicontinuous structures on nanometer length scales. We introduce the topic of dealloying and discuss its phenomenology. Various models of dealloying and porous metal formation are presented. (C) 2003 Acta Materialia Inc. Published by Elsevier Ltd.
