| Abstract Scope |
High entropy alloys (HEAs) have been broadly presented as an ideal structural material, with recent works also showing promise for their functional properties, including magnetic, thermoelectric, catalytic, and biomedical. Recently, we have developed nanostructured HEAs in the form of electrodeposited nanowires of (Cr,Fe,Ni,Co,Cu). These nanowires were then structured to prepare an ultra-low density (<0.1% bulk weight) metamaterial – termed a nanowire scaffold. The nanowires were then welded, resulting in a ridged structure. These structures present new opportunities for specialized applications in weight sensitive technologies and high surface area applications such as catalysts. This work presents the fabrication of the nanowire scaffolds, their structural properties and functional properties (magnetic, thermal). |
