Abstract
The elastic and thermodynamic properties of metallic glasses (Ca70Mg30, Mg70Zn30, Cu57Zr43 and Pd77.5Si16.5Cu6) are obtained from dispersion relations in the low momentum region derived by us for various dielectric screenings, adopting a simple model given by Bhatia and Singh. This model assumes a central force, effective between nearest neighbours and a volume dependent force. For elastic properties, elastic constantsC 11 andC 44 are obtained from slopes of longitudinal and transverse dispersion relations, respectively, whereasC 12 is found by the requirement that elastic anisotropy for disordered systems, like metallic glass, is to be zero. For thermodynamic properties, Debye temperature is calculated for the glasses for various dielectric screenings.
