| Abstract Scope |
Liquid metal dealloying is one of the corrosion modes which is crucial for creating nano- and micro-scale porous materials used in catalysts, fuel cells, and radiation-resistant materials. Primary research has focused on understanding the formation of topological patterns during dealloying. It is revealed that elemental diffusion at the interface between liquid metal and bulk alloy is key to the different topology formations. Here, we developed methods to control the dealloying features using temperature and ion radiation. By exposing Fe-Ni alloys to different temperatures (500C, 600C, 675C) and 3MeV proton radiation in liquid lead, we observed qualitatively and quantitatively changes in topology from sponge-like to motif-like and raindrop-like. Radiation further shifted the topology. This study elucidates how temperature and radiation can be effective ways to manipulate topological patterns in liquid metal dealloying. |
