Characterizations of high entropy alloy powder as catalyst synthesized by mechanical alloying for azo dye degradation
Fe27Co0.27Ni0.27Al0.1Si0.1 and Fe0.27Co0.27Ni0.27(Al0.08B0.02)0.1Si0.1 high entropy alloys were synthesized by mechanical alloying. Phase evolution, crystallite size, lattice strain, microstructure and morphology for the two alloys were investigated. The result shows that two simple structures which...
