Permanent deformation in BCC crystals occurs on the most closely packed planes, and it happens in the most closely packed directions that are {110} planes and <111> directions in the BCC crystal. Assume that a force is applied to a BCC crystal that permanently deforms it in the [001] direction. For permanent deformation that is on a (011) plane:
a) What is the angle between the normal to the (011) plane and the [001] direction? (b) Atomic displacements along what most closely packed directions could contribute to permanent deformation of the crystal in the [001] direction?
