Abstract

The present invention relates to a HEA foam prepared by selective dissolution of a second phase within a two-phase separating alloy comprising the HEA and a manufacturing method thereof. The manufacturing method of the HEA foam of the present invention has the effect of preparing a novel HEA foam, which was not available in the past, by leaving only a first phase after manufacturing a two-phase separating alloy comprising a first phase by HEA, wherein at least 3 metal elements act as a common solvent. Furthermore, the HEA foam of the present invention has a structure, wherein pores are distributed inside the HEA, in which at least 3 metal elements act as a common solvent. By adding a functional characteristic of low heat conductivity, etc., to the existing high strength characteristic of HEA, the HEA foam of the present invention can exhibit a complex effect by the combination of the two particular effects, thereby being capable of exhibiting excellent physical characteristics.
