Synthesis and characterization of AlCoCrCuFeZnx high-entropy alloy by mechanical alloying

Equi-atomic and non equi-atomic multi-component systems were synthesized through different routes to form high-entropy single solid solution. One such high-entropy alloy (HEA) with hexanary composition AlCoCrCuFeZnx was synthesized using mechanical alloying. The effect of zinc variation on the cryst...

Description
Summary:Equi-atomic and non equi-atomic multi-component systems were synthesized through different routes to form high-entropy single solid solution. One such high-entropy alloy (HEA) with hexanary composition AlCoCrCuFeZnx was synthesized using mechanical alloying. The effect of zinc variation on the crystal structure and phase formation was characterized using XRD, FESEM with EDS and TEM. The synthesis resulted in both equi-atomic and non equi-atomic nano crystalline AlCoCrCuFeZn with a crystallite size less than 10 nm.
