Sažetak
In spite of a huge expansion of the research on high-entropy alloys (HEA) their basic understanding is still limited, which is detrimental both for the design of HEAs and for their application. Nevertheless, some properties of a few HEA exceed those of conventional alloys (CA). Clearly, the study of transition from HEA to CA composed from the same constituents is very important both, for understanding the formation of HEA and for proper evaluation of their potential in respect to that of CA. However, this transition has so far been studied in only two types of alloys: crystalline CrMnFeCoNi alloys [1] and amorphous TiZrNbCuNi/Co alloys [2]. Here we review the effects of the transition from HEA to CA on selected properties of these alloys. In both systems the variation of a given property with composition depends sharply on the selected principal component (thus on the interatomic correlations and related electronic structure) and can be either monotonic, or nonmonotonic.
