摘      要：Local arrangement of atoms in supercooled liquid Ni_(80)P_(20) alloy has been investigated by using NPT-MD simulation techniques based on the effective pair Potentials derived for Ni-P system. Bond-orientational order, the long-range correlation function and symmetrical parameters by pair-analysis approach have been calculated for supercooled liquid Ni_(80)P_(20) alloy. Results show. that in case of Ni_(80) .P_(20) alloy, the local structure is all random-like whether the centre of cluster is located at atoms Ni or P. It indicates that the icosahedral symmetry is not the unique model to describe the microstructure in supercooled liquid metals.
