Abstract Scope High-entropy alloys (HEAs) are alloys that are composed of metallic elements with equal or near equal atomic proportions. HEAs are ideal replacements of Fe- and Ni-based alloys for structural applications due to their potential for high strength, high hardness, and good corrosion resistance. For applications such as filters or catalyst substrates, porous structures of these HEAs are of particular interest. In this paper, the production of porous HEA structures by freeze-casting will be discussed. The density of HEAs can be further lowered by adding porosity. Porous HEA structures were produced by freeze-casting FeCoCrNi powders in an aqueous solution, followed by sublimation of the H2O, and lastly sintering of the remaining powder pre-form. The freeze-casting process allows us to create a variety of porous metal structures at a low cost. The HEA foam is characterized using optical microscopy, scanning electron microscopy, X-ray diffraction and micro-Computed Tomography during in situ compression testing.
