Abstract
Structure and mechanical properties of multicomponent high-entropy CoCrCuFeNiSn 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 ∼106 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.
