Slip (materials science) - Wikipedia

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. WebCrystallography is the experimental science of determining the arrangement of atoms in crystalline solids. ... [010], [001] or the negative of any of those directions.
