Nano- to submicro-porous β-Ti alloy prepared from dealloying in a metallic melt

Dealloying in metallic melts has been used to prepare pure base metals with an open-cell porous structure, an example of which is Ti. In this study, previously suggested strategies have been extended to prepare a porous multicomponent Ti alloy of non-equilibrium body-centered cubic phase at room temperature. Dealloying in metallic melts is a promising method for preparing functional nano- to submicro-porous alloys which cannot be prepared by conventional methods.
