Anisotropy of cleavage in B.C.C. transition metals
W.R Tyson,R.A Ayres,D.F Stein +2 more
TL;DR: The problem of predicting the favored cleavage plane in b.c. metals is considered in the light of existing theories of crack propagation as discussed by the authors, and it is shown that both {100} and {110} are likely cleavage planes in the absence of plastic deformation, but that plastic work is least for a ''100'' crack.

Influence of surface energy anisotropy on morphological changes occurring by surface diffusion
A. D. Brailsford,N. A. Gjostein +1 more
TL;DR: The influence of surface energy anisotropy on morphological changes occurring by surface diffusion, on simply shaped bodies, is investigated in this paper, where a preliminary analysis of the equilibrium shape of a two-dimensional body for arbitrary anisotropic is given, the primary aim being to determine the range of validity of the perturbation scheme used in the subsequent time-dependent analysis.

Surface energy, stress, capillary-elastic pressure and chemical equilibrium constant in nanoparticles
A. Sanfeld,A. Steinchen +1 more
TL;DR: In this article, the meaning of the surface stress, surface energy and capillary-elastic pressure (CEP) of solid particles is discussed, and a general relation which links the CEP to the ratio of the chemical equilibrium constant corresponding to nano and large size particles is presented.

Application of the Morse Potential Function to Cubic Metals
L. A. Girifalco,V. G. Weizer +1 more
TL;DR: In this paper, the Morse parameters were calculated using experimental values for the energy of vaporization, the lattice constant, and the compressibility for both face-centered and body-centered cubic metals.

Oberflächenwanderung von Wolfram auf dem eigenen Kristallgitter
TL;DR: In this article, the Gestalt, die die einkristalline Spitze beim Gluhen durch Vermittlung der Oberflachenwanderung annimmt, is not keine Gleich-form with scharfen Kanten, sondern eine verrundete Auflosungsform.

M. Drechsler,J.F. Nicholas +1 more
TL;DR: In this paper, the surface energy of an ideal unstrained cubic crystal at 0°K has been calculated from theoretical calculations of surface energy based on the broken-bond model with a variety of interaction potentials.

The use of the field emission electron microscope in adsorption studies of W on W and Ba on W
TL;DR: In this paper, the authors compared the adsorption properties of W on W and Ba on W on five different planes and concluded that the extent to which these planes develop depends on T and the applied field, F.
