What is Understanding Strain Hardening in Metals about?
Strain hardening, also called work hardening, refers to the strengthening of a metal through plastic deformation. As a metal is plastically deformed, dislocations accumulate which impede further dislocation movement and increase the stress needed for additional deformation. True stress-strain curves are used to model plastic deformation, with the power law approximation commonly used to describe strain hardening. The uniform elongation of a material, or the strain at which necking begins, can be estimated f
