Thermodynamic properties and atomic structure of amorphous zirconium

Sažetak
Wide glass-forming range in Zr-TL alloys (TL=late transition metal) combined with a simple, often linear, variation of their physical properties with composition makes it possible to deduce the physical properties of a pure amorphous zirconium. We explore this possibility by using our experimental results for the magnetic susceptibility ( ) , superconducting transition temperature (Tc), and Young, s modulus (E) of bulk paramagnetic amorphous Zr-(Co, Ni, Cu) alloys extending over a wide composition range. By combining these results with the literature results for the low temperature specific heat of the same alloy systems we obtained set of parameters associated with the electronic structure of the amorphous Zr. The comparison of these parameters with the results of the electronic structure calculations for different crystalline phases of Zr and with the results of the atomic structure studies of the same alloy systems indicate an fcc-like local atomic structure for amorphous Zr. The extrapolated value for E indicates rather weak interatomic bonding in amorphous Zr.
