WebCrystallographic directions are lines linking nodes ( atoms, ions or molecules) of a crystal. Similarly, crystallographic planes are planes linking nodes. Some directions and … 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.
