Crystallographic planes and directions
WebCrystallographic Planes • Miller Indices: Reciprocals of the (three) axial intercepts for a plane, cleared of fractions & common multiples. All parallel planes have same Miller indices. • Algorithm 1. Read off intercepts of plane with axes in terms of a, b, c 2. Take reciprocals of intercepts 3.Reduce to smallest integer values WebThe crystal direction of the rotation axis vectors is labelled on the IPF colour key. [5] Slip in hexagonal close packed (hcp) metals is much more limited than in bcc and fcc crystal structures. Usually, hcp crystal structures allow slip on the densely packed basal {0001} planes along the <11 2 0> directions.

WebCrystallographic Planes: Planes are described by notations, called Miller indices (h k l) • If the plane passes through the origin, select an equivalent plane or move the origin • Determine the intersection of the plane with the axes in terms of a, b, and c • Take the reciprocal (1/∞ = 0) • Convert to smallest integers, clear fractions (optional) • ... WebCrystallographic planes Orientation representation (hkl)--Miller indices Parallel planes have same miller indices Determine (hkl) • A plane can not pass the chosen origin • A plane must intersect or parallel any axis • If the above is not met, translation of the …

WebAll the possible parallelism conditions associated with low-index crystallographic planes and directions in face- and body-centred cubic crystals are enumerated in terms of their minimum angle–axis misorientations. These include the Kurdjumov–Sachs (K-S), Nishiyama–Wassermann (N-W) and Pitsch orientation relationships, which are expressed ...
