Abstract

An MD-simulation of the process of grain-boundary (GB) melting in aluminum is performed. General- and special-type GBs with the [100]-, [110]- and [111]-misorientations are investigated. It is shown that most GBs have lower melting temperatures than that of the single crystal. Grain-boundary melting occurs within the temperature interval from 0.75Тmelt to 0.95Тmelt. Low-angle boundaries and a special Σ11(113) boundary are found to be high-melting.
