摘要：

The paper is concerned with the research of the dynamics of amorphous Ni structure by molecular-dynamics method. Ni was obtained from the melt state by a superrapid cooling. It was shown that the structure of amorphous metals could have at least two variants of the structure, depending on the velocity of cooling. The structure contained conjugated and variously deformed tetrahedrons at the cooling using velocities of 10(14)-10(15) K/s. Franck-Casper phase consisting of conjugated and variously deformed icosahedrons formed at the velocity of nearly 10(13) K/s. The formation of FCC and HCP nanocrystals competing with Franck-Casper phase took place at the above mentioned velocity of cooling.
