| Summary: | The melting mechanism at medium heating rates is unclear, owing to the lack of accurate characterizations of structural changes in poly-directional melting conditions. Here, a particular multilayered nanostructure was selected to control the propagation of melting in a single direction. We predicted the heterogeneous to homogeneous melting (HeM to HoM) transition during a single melting process at medium heating rates of 10–400 K/ps by molecular dynamics (MD) simulations, without a change in heating rates. The information on structural changes for the HeM to HoM transition, including the loss of crystallinity and long- and short-range order, are clearly provided by both a single direction and the radial distribution functions. These results contribute to a more comprehensive understanding of the HeM to HoM transition induced by heating rates. |
