Abstract
A statistical description of metallic glasses is proposed based on evaluation of an entropy and using the concept of potential energy landscape (PEL). The PEL is probed using nano-indentation, assuming that serrations observed are related to local energy levels. Serrations sizes follow a Poisson distribution consistent with, that their formation is a rare events. An entropy is derived revealing parameters characterizing the glass structure. The relevance of the approach is tested on the size effect on mechanical properties of metallic glass. It is noticed that the relations explain the effect of film thickness on the glass transition temperature observed for glass polymers.
