Abstract Scope |
Nanowires are fabricated from a feedstock alloy of equiatomic CrMnFeCoNi via growth into the nanocavities of an alumina mold. The mechanism of growth is shown to proceed via both dislocation slip and interface diffusion at different temperatures, while bulk diffusion is considered but not observed. The effects of temperature, pressure, and alumina dimensions on nanowire composition, length, and structure are investigated, giving insight into interdiffusion among the alloy elements. Further, interfaces between feedstock alloy, alumina mold, and nanowires are observed and considered. These results will enable the fabrication of high aspect ratio nanowires of high-entropy alloy systems and help to better understand their fast and sluggish diffusion processes. |
