Abstract
Three effects define deformation‐twinning based metal strengthening: reduction of the free slip distance (Hall‐Petch effect), transformation of glissile to sessile dislocations (Basinski mechanism), and, additionally, textural softening due to reorientation of the material to a favourable orientation for slip. The relative contributions of these mechanisms govern the hardening process and provide a basis for its prediction in alloy design.Keywords
