Abstract
Aging effects on the dynamics in liquid Al2O3 models at the temperatures of 3500 and 5600Â K have been investigated using molecular dynamics simulations. Simulations were done in the basic cube under periodic boundary conditions containing 3000 ions with Born-Mayer type pair potentials. Calculations show that aging slightly affects mean-squared atomic displacement and diffusion constant and it reduces diffusion constant of components in the system. We compare the partial radial distribution functions (PRDFs) for the 10% most mobile or immobile Al or O particles with the corresponding mean ones. We find no effect of aging on such PRDFs in the system. Furthermore, we find significant aging effects on cluster size distributions of 10% most mobile or immobile particles in the system.
