| Abstract Scope |
HEA is a single solid solution or composite of some solid solutions, which are thermos-dynamically understood that maximizing the configurational entropy stabilizes ductile solid solutions by suppressing generation of brittle intermetallic compounds. People are applying HEAs for heat-resistant materials due to its high thermodynamic stability in the high temperature region, as well for corrosion-resistant and radiation-damage-resistance materials using their novel characteristics. If nanoporous HEA is developed, we can find excellent functional properties for new HEA applications, such as catalysts, electrodes and so on, due to its huge specific surface area. In this paper, we introduce, in the beginning, the dealloying technique by which we can prepare self-organized porous metals with bi-continuously connected nano- or micro-meter pores, then, design porous HEAs using this dealloying technique. |
