Primes¶
- Defect
- The macroscopic property is set by the distribution and dynamics of defects rather than by the bulk — a metal's strength is fixed by dislocation density, not by perfect-lattice properties.
This sourceEstablishes that a metal's strength tracks dislocation density rather than perfect-lattice properties, and that dislocations glide along slip planes to permit plastic deformation at a fraction of the theoretical stress.

- Dislocation Motion
- The ordered substrate is the crystal lattice, whose atoms sit in well-defined positions; simultaneously shearing one whole plane of atoms past another — breaking every bond at once — would require an enormous stress, the theoretical shear strength.
This sourceStandard text on dislocation glide, cumulative slip, work hardening, and pinning (precipitates, grain boundaries) as strengthening mechanisms.
