Crystallographic direction families
WebApr 1, 2024 · The pole figures quantify the texture intensity for three crystallographic direction families <001>, <101> and 〈111〉 with respect to the front view of the sample (top surface). On the other hand, inverse pole figures are 2D representations of orientations. IPFs can be plotted as points and each point represents sample direction.

WebCrystal structure is described in terms of the geometry of arrangement of particles in the unit cells. The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. The geometry of the unit cell is defined as a parallelepiped, providing six lattice parameters taken as the lengths of the cell edges (a, b, c) and the angles … WebOctober 1995 Crystallographic Notation Lattice Position 1 2 1 4 0 Position in a unit cell: coordinates measured along axes in units of corresponding cell dimensions. Each coordinate is thus 0 or a proper fraction, except that in NaCl-type crystals the unit-cell dimension is often taken as 2. Symbols based on Miller Indices
