Abstract

Methods of non-linear physics allowed determination of universal attributes of non-equilibrium systems, conditioned by collective effects and self-organization phenomena in the arising dissipative structures. The paper presents data on the rate of centers formation of a number of studied metals, time-temperature regularities of the dynamic failure process, that permit modeling metals behavior under laboratory conditions and predict time boundary of maintaining functional properties under extreme conditions (longevity range t ∼ 10⁻⁶ − 10⁻¹⁰ s).
