Mechanical Properties of Amorphous Metallic Alloys and Their Relation to the Viscosity Characteristic Parameters
The unified theoretical equation of B. Yang et al. on the relation between the mechanical strength and viscous flow behavior of glassy metals is presented and discussed; it is shown that the equation of Yang can be successfully used for estimation of fraction strength of various ribbonlike glassy metals, provided that their viscous flow behavior is precisely determined under nonisothermal experimental conditions. The viscous flow and mechanical properties of Co100-x Zrx and Cu100-xZrx glassy alloys are presented and discussed, together with their comparison with the data existing in the bibliography. A relation between the estimated fraction strength of glassy alloys and their Vickers microhardness is established.
