Chernysheva // Inorganic Materials. - 1999. - V.35, N1. - С. 42-48 Рубрики: ФИЗИКА Кл.слова (ненормированные): STUDY MOLECULAR-DYNAMIC -- CRYSTALLIZATION -- SODIUM -- Na -- SODIUM LIQUID -- SODIUM SUPERCOOLED -- CRYSTAL NUCLEATION -- HOMOGENEOUS NUCLEATION -- SIMULATION -- RUBIDIUM -- Rb -- MODEL Аннотация: Crystallization of supercooled liquid sodium containing a spheroidal bce nucleus was studied by molecular dynamics simulations. The degree of supercooling and the critical nucleus size are determined. After solidification, the system exhibits elasticity of shear. Nucleus growth is accompanied by self-sustained aperiodic temperature oscillations. The radial distribution function is computed and Voronoi polyhedra are constructed for the system immediately before and after the transition. It is shown by the projection method that the crystallized system contains structural defects and Features a long-range order |
