An increase in resistance to further plastic deformation after deformation has changed the microstructure. Increasing dislocation density and interactions can impede subsequent dislocation glide.
Increase in the resistance of one slip system caused by plastic shear on another. It can shift the onset of secondary slip away from a purely geometric equal-Schmid-factor prediction.
Resistance to dislocation glide produced by intersections with other dislocations. Multiple active slip systems can form junctions and increase the density of obstacles. This is one mechanism of work hardening.

Work hardening, also known as strain hardening, is a phenomenon that occurs in materials, particularly metals, where the material becomes stronger and harder as it is subjected to mechanical deformation. This process is a result of dislocation movements and interactions within the material's microstructure during deformation. When a metal is deformed (e.g., stretched, compressed, or bent), dislocations in its crystal structure move.
