| CONVERTING OF THE ENERGY OF SUPER-POWER ELECTROIMPULSES IN FLUIDIC METALS |
| The problem of making of new steels and alloys is tightly bound to searching the effective physical analogs adequately circumscribing converting of energy of exterior action at phase modular passages. One of the most perspective modes of shaping of special metal materials on a base of few - arborescent metal lower dies is electrocurrent impulse treatment /ECIT/ on a method of academician Korneev [1-3, 7]. Innovational essence of Korneev ECIT consists in special algorithms of feeding of series of superhigh-energy electroimpulses through solidifying metal and is accompanied by a series of nontrivial physical processes. The assaying of these processes has allowed revealing singularities of their phenomenological thermodynamics, the bound with kinetic evolutions of lapse rates of thermo-fields and generation of thermo-wave packets [3 - 6]. |

| METAL RECRYSTALLIZED SEECPT - EFFECTS |
| Action of superhigh-energy electro-current pulsing treatment /SEECPT/ on a method of academician D.I.Korneev on is primary the hardened melt is closely bound to such composite and diversiform phenomenon, as a grain recovery. The grain recovery is one of widely enough widespread processes, metals forming structure, steels, and alloys at a stage of secondary solidification. In a base of such shaping change of a degree of anisotropy structurally sensing mechanical and physical properties of the metal-lattice lower dies, including their internal geometry, between crystallite orientation and a degree of perfection of making sinters micropolycrystallite lays. At an equilibrium grain recovery, in absence of complex action of destabilizing factors /CADF/, the course of processes of secondary reorganization of the lattice lower dies is defined by temperature modes of order-disorder transformation submicrostructure localizations. Let us note that in the metal materials, which are not testing a phase recrystallization, warp and the subsequent grain recovery are prevailing means of metalmatrix's structure change. |

| ABNORMAL ANTICORROSIVE ECPT-EFFECT |
| The all-round analysis of processes of rust resistance of metals and the alloys subjected superhigh-energy electrocurrent pulsing treatment /ECPT/ in a stage of hardening on a method of academician Dmitry I. Korneev, has allowed to reveal a lot of paradoxical function dependences [1 - 4]. Connections between a degree of granularity of recrystallized matrixes and speed of corrosion degradation are distinctly displaid depending on modes of complex influence of destabilizing factors /CIDF/. It, undoubtedly, raises value of use ECPT at the control and management of processes of hardening of melts over welding and metallurgical production. Influence of a degree of granularity of textures on corrosion behavior of recrystallized metals traditionally connects to a level of the maintenance of superficial micropores, heterogeneous inclusions, and homogeneous liquation. Similar stoichiometrical infringements of the polycrystalline order have the expressed centers of concentration, which are settling down mainly on borders of grains, more often. The conclusion that coarse-grained dendritic screen matrixes are predisposed to occurrence of the centers of the superficial corrosion considerably worsening mechanical service characteristics of metals and alloys from here follows. In a basis of physical theories of metallic corrosion after ECPT the experimental data connecting change of speed of crystal-amorphous hardening with size of entered electromagnetic energy lay. |

| Passage of high-energy electrocurrent impulses through molten metal are a base of the unique metallurgical method unclosed, explored, and designed outstanding a physics of metals academician D. I. Korneev. At passing operating currents of electrocurrent pulsing treatment /ECPT/ on D. I. Korneev algorithm, operation of a lot of nonstandard transformation's mechanisms of the electromagnetic energy reserved in a discharge circuit is initiated, thus in a melt of metal the structure of the initial treelike streamers testing an intensive dissipation is formed. Further plasma formations of a electric discharge channel's trunk /EDCT/ will be transformed to spanned cords and in part stabilized. The colliding shock dispersion of loose electrons in singlet sense and repeatedly ionization atoms of metal results in a heating-up and transpiration of a melt inside EDCT. Intensive process of filament formation on base EDCT is accompanied by formation of the plasma cords twisted on century braids by a peak-a-boo electromagnetic field. Finally, there is a plasma-discharge conductor of electromagnetic energy of an external contour [1 - 3]. EDCT represents the composite energy formation from hot plasma and is in a metastable state of an unstable balance. Simultaneously, local diffusive streams of charge carriers will flow off in boundary regions EDCT, labializing colliding processes of the secondary ionization [4]. |
