摘要：

This paper concentrates or, tuning the morphology of nanoporous metals, in particular Au, as a function of the dealloying potential. Ligament diameter and pore size were evaluated from digital image analysis and from measurements taken directly from scanning electron micrographs. Linear relationships were observed between the dealloying potential and the size of ligaments and pores. At a low dealloying potential the pore size is larger than the ligament diameter but at a high dealloying potential they are comparable. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd.
