Outline of Final Research Achievements

Effects of current flow on the dealloying reaction using liquid medium were studied. When Fe-Ni binary alloy precursor was dealloyed by pure Mg solid, a significant difference on the reaction kinetic was observed, depending on the direction of current flow. That is, a reaction kinetic was accelerated when the current flow is from Fe-Ni precursor to Mg. On the contrary, morphology of the porous metal formed was almost independent on the presence or direction of current flow.
