Strategies for strengthening: grain size reduction
Grain boundaries are barriers to
slip.
Barrier "strength increases with
increasing angle of misorientation.
Smaller grain size: more barriers
to slip.

Dislocation and plastic deformation
Cubic & hexagonal metals - plastic deformation by plastic shear or slip where
one plane of atoms slides over adjacent plane by defect motion (dislocations).
If dislocations don't move, deformation doesn't
