Abstract
From the molecular dynamics simulation on the microstructural transitions of Al liquid metal during rapid cooling, various aggregates are formed in both liquid state and glassy state. Some aggregates are relatively stable and can not be dissociated in the following runs. The stability of icosahedral aggregates can be expressed quantitatively by their lifetime or repeating times. The lifetime increases with the decrease of temperature, especially increases remarkably below the glass transition temperature. The number of aggregates having a longer lifetime also increases with the decrease of temperature.
