is dependent on the shear modulus, G, the magnitude of the Burgers vector, b, and the dislocation density, :
:

where is the intrinsic strength of the material with low dislocation density and is a correction factor specific to the material.

As shown in Figure 1 and the equation above, work hardening has a half root dependency on the number of dislocations. The material exhibits high strength if there are either high levels of dislocations (greater than 10¹⁴ dislocations
