Geometry of the Crystal Lattice of β-Tin

The arrangement of atoms in a β-tin crystal lattice is studied. Interplanar spacings between lattice planes and the minimum atomic distances in glide are calculated. Geometrical approaches are carried out on the stacking of lattice planes and the atomic arrangement of jogs which are produced by intersection of dislocations or emission of vacancies. The results are discussed in connection with the reported slip systems and the observed phenomena in plastic deformation. Elastic interaction between a slip and a forest dislocation is studied, and the force exerted on each part of the slip dislocation and the total force are calculated for every combination of relative locations and Burgers vectors of both dislocations.
