2.3 LATTICE RESISTANCE TO DISLOCATION MOVEMENT: THE PEIERLS
STRESS From Fig. 2.3 it is clear that the insertion of the extra half plane of atoms
has perturbed the lattice and caused atoms to be pushed aside laterally,

For example, yield-strength temperature and strain-rate sensitivity varies with the
Peierls stress component of the ... steels, the Peierls stress increases rapidly with
decreasing temperature, thereby causing these materials to exhibit a sharp rise ...
