Originální abstrakt

High and medium entropy alloys are an intriguing new material class, revered for possessing an exceptional combination of primarily mechanical properties. In this scientific contribution, the CoCrNi medium entropy alloy has been produced by a combination of mechanical alloying (MA) and spark plasma sintering (SPS). The properties have been characterized by means of X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and tensile testing. The powder after the MA process exhibited nano-grained microstructures with fine chemical homogeneity. After the SPS densification, a full density of the bulk products has been achieved. The microstructure was composed of major FCC phase and minor secondary precipitates. The materials possessed high strength values coupled by reasonable ductility levels, therefore overall satisfactory results.
