Structure and properties of high-entropy CoCrCuFeNi[Sn.sub.x] alloys

Structure and mechanical properties of multicomponent high-entropy [CoCrCuFeNiSn.sub.x] alloys (x = 0.5; 1.0) have been studied for the first time in the as-cast and splat-quenched (at a rate of ~[10.sup.6] K/s) states. The simultaneous formation of two solid solutions has been established in the al...

Zusammenfassung:Structure and mechanical properties of multicomponent high-entropy [CoCrCuFeNiSn.sub.x] alloys (x = 0.5; 1.0) have been studied for the first time in the as-cast and splat-quenched (at a rate of ~[10.sup.6] K/s) states. The simultaneous formation of two solid solutions has been established in the alloy structure. High values of the microhardness and dislocation density have been obtained in the splat-quenched samples. Keywords: high-entropy alloy, structure, microhardness DOI: 10.1134/S0031918X14040024
