that the interface structure affects the stability of interfaces and the asymmetrical growth of the amorphous phases. The energies and mobilities of interfaces on the evolution of the microstructure had... alloys. It is found that this method can study not only the microstructure evolution but also the atomic behavior of interface migration[13]. In the present work, we investigated the atomic structure......
