Abstract

Metallic glass-forming liquids and glasses are ranked using thermophysical properties (glass transition, excess entropy, fragility indexes). The relationships between mechanical properties and some of the above quantities are discussed to get insight into the mechanism of shear band propagation during mechanical failure when, following up a shear offset event, a local temperature rise occurs. The mechanism is supported by evaluating the energy content of the shear band, as well as finite element modelling of temperature profiles around it.
