Sažetak
A study of transition from conventional multicomponent alloys to high-entropy alloys (HEA) is important both for understanding the formation of HEAs and for proper evaluation of their potential in respect to that of conventional alloys. We report main result of a such study performed on (TiZrNbNi)1-xCux metallic glasses (MG) over a broad concentration range x≤0.52 encompassing both HE-MGs and Cu- base MGs. A comprehensive study of the composition, homogeneity, thermal stability, atomic structure, electronic structure and magnetic susceptibility of eleven alloys has been performed. Thermal analysis revealed rather weak variation of thermal parameters and glass forming ability with x. Study of atomic structure showed a linear variation of average interatomic distances and atomic volumes close to these predicted by Vegard`s law. The coordination numbers and atomic packing fractions were constant throughout the explored concentration range. The electronic density of states (DOS) showed a split-band structure with DOS close to the Fermi level dominated with d- states of Ti, Zr and Nb. Accordingly, magnetic susceptibility decreased linearly with x and extrapolated to that of Cu. Thus, studied alloys show ideal solution behaviour similar to that of binary Cu-Ti, Zr, Hf MGs. The results are compared with those for (TiZrNbCu)1-xNix MGs and (CrMnFeCo)1-xNix alloys and their impact on understanding the transition from HE-MGs to conventional MGs with the same composition is briefly discussed.
