| Abstract Scope |
In this study additive friction stir deposition (AFSD) was used to fabricate a bulk Al0.04CoCrFeNi high entropy alloy deposit from arc cast feed stock. Phase analysis via x-ray diffraction indicated the presence of equilibrium phases after deposition. The grain structure and material mixing were examined using electron backscatter diffraction (EBSD) and energy dispersive spectroscopy (EDS) respectively. Significant grain refinement was observed in the AFS-D deposit in comparison to the feed stock with features indicative of dynamic recrystallization. The refined microstructure resulted in increased microhardness. The results are discussed relative to cast and wrought HEAs having the same or similar composition. |
