The mechanism of strain localization of polycrystallic precipitation hardening materials based on the account of statistical dissipation in allocation of particles on slip planes and dissipation of the size of particles is proposed. The methods of computer simulation have shown that the decrease of the grain size of precipitation hardening alloy and the decrease of particles amount, contained in a grain and also the formation of particles polydisperse mixture at thecoagulative growth stage during aging, intensify the dissipation in allocation of particles on a matrix.
