Prediction of surface properties of metals from the law of corresponding states
The schema, previously developed by the author, for the prediction of surface tension of liquid metals (LM) from the corresponding states (CS) principle has been extended to solid metals (SM). As in the case of LM, the reduced formula for surface tension of SM has been obtained by scaling E and a characterizing the interatomic potential, with the melting point T-m(0) at atmospheric pressure and the atomic volume Omega(sm)(2/3)(0)\(rm) at the melting point as macroscopic parameters. Sill CS rules derived for the surface tension, its temperature derivatives, and also the specific surface energy are discussed and compared with the experimental data and with the counterpart rules for LM. It is shown that pressure dependence of the surface tension can be described by pressure dependence of the scaling parameters T-m(p) and Omega(m)(p). (C) 2002 Elsevier Science B.V.
