The kinetics of irreversible structural relaxation and rheological behavior of metallic glasses under quasi-static loading

Abstract

It is shown that the directional structural relaxation (DSR) model supplemented by the Maxwell rheological model allows the derivation of a set of simple equations that describe within a common framework a number of mechanical relaxation phenomena induced by irreversible structural relaxation of metallic glasses under quasi-static loading. A comparison of the model predictions with literature experimental data is made. It is concluded that the equations derived are supported by available experimental findings.
