Abstract Scope |
To attain low density and good mechanical characteristics, a quaternary AlCoCrNi alloy was created by eliminating the heavy ingredient of Fe from the dual-phase AlCoCrFeNi high-entropy alloy. The Cr-rich A2 and Ni(Co)-Al-rich B2 phases of the AlCoCrNi alloy had a high degree of coherence in both dendritic and interdendritic areas, and the alloy had a nano-scale dual-phase structure. The non-stoichiometric composition between Ni and Al was discovered in the Ni(Co)-Al-rich B2 phase, which differed from the Ni-Al-rich B2 phase with a stoichiometric composition in the earlier AlCoCrFeNi high-entropy alloy. The mechanical characteristics of the dual-phase high-entropy alloy were heavily influenced by chemical development in the component phases. The mechanical characteristics of the AlCoCrNi alloy were extensively examined across a wide temperature range based on these microstructural features. |
