Abstract

The effect of the scale characteristics of a nanodispersed hardening phase on the strain hardening and evolution of the defect subsystem in materials with an fcc matrix has been studied with the use of a mathematical model including differential balance equations for the components of the strain defective subsystem. The two-stage character of evolution of the strain defect subsystem and the possibility of plastic shearing in dispersion-hardened materials due to either the motion of individual dislocations or the generation of numerous dislocations in the shear band were taken into consideration.
