Crystallographic planes and directions
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) • ...
