Compared with typical nanocrystalline (nc) metals and alloys, nc high-entropy alloys (HEAs) exhibit exceptional mechanical properties with satisfied thermal stability. Typical methods for producing nanocrystalline HEAs usually requires severe mechanical deformation. Upon heating, grain size grows rapidly, limiting their applications at elevated temperatures. Here, we investigate a series of equiatomic binary NiCo, ternary NiCoFe, NiFeCr, and quaternary NiCoFeCu nanocrystalline alloys, produced using electrodeposition. The alloys were subsequently processed with heat treatment at temperatures in the range 573-823 K. Nanoindentation were applied to identify the temperature dependency of mechanical properties. Our study demonstrates a scalable method for producing high-strength and thermally stable HEAs.
