The Hall–Petch relation correlates yield stress with

Show Hint

To remember the Hall–Petch behavior, connect it with grain boundary strengthening: Smaller grains mean more boundaries, more boundaries lead to more dislocation pile-ups, and more pile-ups require a higher yield stress to cause deformation.
