Abstract

Based on the theory of micro-inhomogeneity of liquid metal, a calculation model is established for the quantitative description of the structural information of metal melts. Only by thermophysical property parameters and basic structural parameters of solid metal, can this model produce the main information of melt structure, including the relative concentration of active atoms, size of atomic clusters and number of short-range order atoms. Based on this model, the main structural information of Al and Ni melts in the not high range above the liquidus is calculated, with results in good agreement with experimental values. Besides, analyzed is the influence of superheating temperature and atomic number on the melt structural information of the first (IA) and second main group (IIA) elements. With temperature increasing, melt structural information regularly changes for both IA and IIA elements. With the atomic number increasing, melt structural information of IA elements changes regularly, for the crystal structures of the IA elements are all of bcc lattice type. However, no notable regular change of melt structural information for IIA elements has been found, mainly because the lattice type of IIA elements is of hcp-fcc-bcc transition. The present work presents an effective way for better understanding metal melt structure and for forecasting the change of the physical property of metal melts.
