Abstract
- Recent studies (J. Alloys Compd. 695 (2017) 2661) of the electronic structure and properties of $(TiZrNbCu)_{1-x}$$Ni_{x}$ (x$\leq$0.25) amorphous high entropy alloys (a-HEA) have been extended to x=0.5 in order to compare behaviours of a-HEA and conventional Ni-base metallic glasses (MG). The amorphous state of all samples was verified by thermal analysis and X-ray diffraction (XRD). XRD indicated a probable change in local atomic arrangements, i.e. short-range-order (SRO) for x$\geq$0.35. Simultaneously, thermal parameters, such as the first crystallization temperature $T_{x}$ and the liquidus temperature showed a tendency to saturate for x$\geq$0.35 . The same tendency also appeared in the magnetic susceptibility $\chi_{exp}$ and the linear term in the low temperature specific heat {\gamma}. The Debye temperatures and Youngs moduli also tend to saturate for x$\geq$0.35. These unusual changes in SRO and all properties within the amorphous phase seem correlated with the change of valence electron number (VEC) on increasing x.<br />Comment: 13 pages, 6 figures
