Abstract
There are established the boundaries of conserving functional properties of metals at dynamic failure under extreme conditions (longevity range t ∼10−6 ÷10−10 s). The methods of non-linear physics made it possible to determine universal attributes of non-equilibrium systems evolution conditioned by collective effects and phenomena of self-organization in the appearing dissipative structures. In the paper there is presented a universal failure surface that allows simulation of metals behavior under laboratory conditions and forecast of time boundary of functional properties conservation.
Highlights
Today quite acute is the knowledge of material behavior under extreme conditions, in highly non-equilibrium states when the value of energy variation from the equilibrium state is compatible to the energy of phase transition, for example
At small degrees of deviation from equilibrium the relaxation processes are determined by kinetics mechanisms that are described by the classic kinetics instrument
In the failure physics in a quasi-static longevity range the time interval up to failure is determined by the time of critical fluctuation formation, for example, energy leading to destruction of a part of atomic bondings
Summary
Today quite acute is the knowledge of material behavior under extreme conditions, in highly non-equilibrium states when the value of energy variation from the equilibrium state is compatible to the energy of phase transition, for example. Acute is the investigation of the entire sequence of events preceding the threshold state as well as determination of time boundary of functional properties maintainance for a set of metals under extreme conditions.
