Molecular dynamics simulations were made of structural changes due to quenching the melting interface at a Σ5 (310)/[001] symmetrical tilt grain boundary. The simulation results suggested that the grain boundary structures due to quenching were different to those due to heating up to the same temperature. The calculated atom density profiles showed that the grain boundary structures could be significantly changed as they were quenched to quite low temperatures.
