A COMPLETE CHARACTERIZATION OF THE RELATIVE SURFACE-ENERGY ANISOTROPYIN METAL CRYSTALS

Within the framework of a broken bond model applied to the (001) plane rotated about axes [0101, [110], [210], and [310], a complete charact erization of the relative surface energy anisotropy in metal crystals with face-centered cubic, body-centered cubic and hexagonal close-pack ed lattices has been given. The anisotropic surface-energy distributio n on the spheres of gnomostereographic projections is characterized by a minimum at poles [111] and [001] (FCC), [110] (BCC), [00.1], [10.0] and [10.1] (HCP) and by a maximum at poles [102] (FCC), [117] and [11 1] (BCC), [11.4] and [11.1] (HCP-crystals).
