Abstract

Surface energies of hexagonal close-packed (hcp) crystals for three families of lattice site planes have been computed and their angular correlations have been determined. The broken bond method and the model of stepped microprojections of crystal faces were employed. The atomic interactions were taken into account in two coordinate spheres. Relative surface energies have been computed for Be, Cd, Co, Hf, Mg, Ti, Zn, Zr. The theoretical results are compared with experimental data.
