Originální abstrakt

A metal matrix composite - consisting of a matrix of medium entropy alloy CoCrNi and Mo as reinforcement - is reported on the present study. The composite was produced by mechanical alloying (MA) in combination with spark plasma sintering (SPS). The investigation of the microstructural features, chemical composition and basic mechanical properties of the bulk material were subject to study, by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDS) and Vickers microhardness testing. A full-density composite has been achieved with the selected sintering conditions, showing an average hardness of 514 HV0.3. Its' microstructure exhibited four different phases, possessing a matrix consisting of FCC solid solution reinforced by BCC particles surrounded by a μ-phase in the interface of the matrix/reinforcement and dispersed HCP precipitates.
