“…Nevertheless, the results of recent studies show that the classical nucleation theory can have limited applicability when the size and the distribution of cavities within the material are weakly dependent on its thermodynamic state [7,12,13]. Such conditions can be realized, for example, at testing metals for creep [14]. Also, for the correct description of the early stage of the cavity formation in the framework of the classical theory, it is great importance to identify correctly stable "viable" cavities and to determine the dynamics of changes in their size.…”

Understanding the cavity formation and cavity growth mechanisms in solids has fundamental and applied importance for the correct determination of their exploitation capabilities and mechanical characteristics. In this work, we present the molecular dynamics simulation results for the process of homogeneous formation of nanosized cavities in a single-component amorphous metallic alloy. To identify cavities of various shapes and sizes, an original method has been developed, which is based on filling cavities by virtual particles (balls) of the same diameter. By means of the mean first-passage time analysis, it was shown that the cavity formation in an amorphous metallic melt is the activation-type process. This process can be described in terms of the classical nucleation theory, which is usually applied to the case of first order phase transitions. Activation energy, critical size and nucleation rate of cavities are calculated, the values of which are comparable with those for the case of crystal nucleation in amorphous systems.
