摘要
We have performed molecular dynamics simulations of structural changes due to quenching the melting interface at a Cu ∑5（310）/[001] symmetrical tilt grain boundary, The simulation results suggest that the grain boundary structures due to quenching are different from those due to heating up to the same temperature. The calculated atom density profiles show that the grain boundary structures can be significantly changed as they are quenched to quite low temperatures.
