摘要：

The microstructure evolution of the supercooled Ni(3)AI melt and the kinetic details of the crystalline nucleation in the melt were investigated using the molecular dynamics simulation method. It is indicated that the non-crystal atomic clusters disappear from the melt before the beginning of the nucleation. The crystal nucleus is a random mixture of fcc structure and hcp structure and shows an irregular shape.
