One slip system for the HCP crystal structure is
{0001}(1120). In a manner similar to Figure 7.6b,
sketch a {0111}-type plane for the HCP structure
and, using arrows, indicate three different (1120)
slip directions within this plane. You may find
Figure 3.9 helpful.
One slip system for the BCC crystal structure is {110} . Sketch this
plane along with the BCC atoms and identify two different slip directions
within this plane.
