Abstract

A mathematical model of plastic strain in monocrystals of dispersion-hardened FCC materials with nanosize particles of the second phase is used to investigate the influence of the temperature and strain rate on the behavior of the material and evolution of its dislocation subsystem. It is established that the curves of the temperature dependence of work hardening and density of various dislocation subsystem components for materials with different (aluminum, copper, and nickel) matrices differ insignificantly.
