Brief historical background about the unit

In 1982 At the Tomsk School of Solid State Physics and Materials Science, 2 conceptually new provisions in the field of plasticity and strength of solids were formulated and published:

1. Structural levels of deformation of solids (Panin V.E., Grinyaev Yu.V., Elsukova T.F., Ivanchin A.G.  Izv. universities. Physics. - 1982. - Issue 25. - No. 6 . - P. 5-27.)

2. Atom-vacancy states in crystals (Panin V.E., Egorushkin V.E., Khon Yu.A., Elsukova T.F. Izv. universities. Physics. - 1982. - v. 25. - No. 12. -p. 5-28).

A fundamentally new methodology was proposed for describing plastic deformation and fracture of solids. It was qualitatively different from existing concepts in continuum mechanics and dislocation theory  and at first caused a sharply negative reaction. It took more than a quarter of a century to substantiate a new paradigm of plasticity and strength of solids on the basis of convincing theoretical and experimental research and gain its recognition. This was the main scientific direction of the new Institute of Strength Physics and Materials Science of the Siberian Branch of the USSR Academy of Science, created in Tomsk in 1984.

Various divisions of the young Institute were distributed to solve the most pressing problems of a promising scientific direction, from its methodology to the applied development of new materials and technologies.

Research areas, areas of fundamental research

Physical mesomechanics of materials and nanomaterials, nanomaterial science, diagnostics of nanostructured materials

Tasks solved within these areas

The following tasks were set for the laboratory of physical mesomechanics of materials and non-destructive testing methods:

1.   Formulate and justify the basic methodological principles of physical mesomechanics.

2.   To develop new methods for experimental study of the patterns and mechanisms of plastic deformation and fracture at mesoscale structural levels of hierarchically organized solids.

3.   Show the important functional role of the planar subsystem (surface layers and internal interfaces) in the initiation and development of plastic deformation and fracture of solids.

4.   Involve nonequilibrium thermodynamics for a self-consistent description of the formation of defective substructures at various scale levels up to the destruction of a deformable solid.

5.   Investigate the thermodynamic nature of local structural transformations during the nucleation and propagation of deformation defects of various types. Show the decisive role of highly excited states in local zones of lattice curvature and  hydrostatic stretching in the initiation of all types of deformation defects, including cracks.

6.   Based on a multi-level approach of physical mesomechanics, develop new materials with nanostructured subsystems and solve current applied problems: non-destructive testing methods, fatigue failure criteria, wear mechanisms of materials on friction surfaces, hardening of surface layers and application of strengthening coatings in order to increase the strength, wear resistance and fatigue life of structural , instrumental and functional materials.

The tasks assigned to the laboratory could be solved only in conditions of close integration with other laboratories of the institute: theorists, experimenters, technologists, as well as with other institutes. The effectiveness of such integration is presented in the sections “the most important scientific results” and “the most important publications”. Organizationally, this is presented in the form of the implementation of complex programs of the SB RAS, Integration projects of the SB RAS, projects of the Presidium and Branches of the RAS, projects of the Russian Foundation for Basic Research, projects of Presidential support of the Tomsk scientific school, as well as federal targeted program projects. Among the major applied works, special mention should be made of cooperation with the Federal State Unitary Enterprise VIAM, Sukhoi Design Bureau, and the Keldysh Center.

The most important scientific results

Under the leadership of Academician V.E. Panin has created and is developing a new scientific direction - physical mesomechanics of materials, which organically combines the mechanics of a continuous medium (macro level), the physics of plastic deformation (micro level) and physical materials science.

1. The fundamental principles of physical mesomechanics are formulated, theoretically and experimentally substantiated: description of a deformable solid body as a hierarchically organized multi-level system in which surface layers and internal interfaces are an important functional planar subsystem; the unified nature of all mechanisms of plastic deformation and destruction of solids, which is based on the nanoscale structural level of local structural transformations; movement at the mesolevel of three-dimensional structural elements as a whole according to the “shift + rotation” scheme; particle-wave dualism of plastic shear; destruction as a nonlinear wave process of global loss of shear stability of a loaded solid at the macroscale level, when the thermodynamic Gibbs potential of the material in the destruction zone changes its sign from “-” to “+”.

2. The nonequilibrium thermodynamics of a deformable solid as a self-consistent multilevel system has been developed. Based on the dependence of the nonequilibrium thermodynamic Gibbs potential F(v)on the molar volume v and multi-level structural studies have shown that all types of deformation defects, including cracks, originate as local structural or structural-phase transformations in hydrostatic tension zones of various scales, in which highly excited states and collective configurational excitations arise. The nucleation of deformation defects and cracks is described by the laws of nonequilibrium thermodynamics. Mechanics creates the necessary conditions for this (the formation of zones of lattice curvature and hydrostatic tension in gradient fields of non-uniform internal stresses). The use of nonequilibrium thermodynamics in mechanics makes it possible to construct a generalized multi-level model of a deformable solid for any materials and under any loading conditions.

3. It has been shown that in the nanoscale range d<100 nm, near the zero of the Gibbs thermodynamic potential at d<30 nm, pre-transition two-phase nanostructural states arise, in which nanocrystals withF (v)<0 are surrounded by a quasi-amorphous phase with F(v)>0. Such states define a special class of nanostructured materials that form the basis of nanoengineering. Materials with a structure in the size range [100-30] nm should be called nanosized. The criterion d=100 nm has no physical basis.

4. It has been shown theoretically and experimentally that at the interface of two dissimilar media in the fields of external influences, a “chessboard” distribution of normal and tangential stresses arises, which causes the formation of a regular corrugation of the interface, a change in its composition, structure and properties, cracking and delamination of the multilayer system, and an increase in its chemical and catalytic activity. The strong influence of nanostructuring of interfaces on all these effects is substantiated. The principles of designing interfaces in multilayer nanostructured coatings for various functional purposes and at internal interfaces in heterogeneous structural materials, which determine their service life under extreme loading conditions, are formulated. Nanotechnologies have been developed for the formation of multilayer nanostructured strengthening, protective and functional coatings.  Together with the Keldysh Center, multilayer nanostructured heat-protective coatings for rocket and space technology have been developed, capable of operating effectively in extreme conditions of high-temperature plasma flows.

5. A comprehensive analysis of the physical nature of the refinement of the crystalline structure of metallic materials during their severe plastic deformation (SPD), including the thermodynamic foundations of highly nonequilibrium states, the evolution of a highly inhomogeneous stress-strain state was carried out. and structural and kinetic aspects. A general conclusion has been made that structure refinement during SPD is associated with fragmentation of crystallographic lamellas between meso- and macrobands of localized deformation. The maximum dimensions of structure refinement are determined by the structural-scale levels of strip structures, gradient fields of inhomogeneous internal stresses and kinetic conditions of thermodynamic recovery processes, including cold dynamic recrystallization, in highly nonequilibrium zones of strip structures.

6. A fundamentally new concept about the fundamental role of local lattice curvature in plastic deformation and fracture of solids is substantiated. All types of deformation defects are considered as curvature solitons of various scale levels, which originate in zones of lattice curvature and prevent their growth to a critical value when the crystal undergoes structural-phase decomposition and collapses. Plastic deformation is considered as the evolution of a dynamic system of self-organized criticality, which is associated with the scale level of lattice curvature.

7. A fundamentally new model of plastic deformation and fracture of solids has been developed, associated with their evolution to self-organized criticality, determined by the self-consistency of all mesoscale levels of lattice curvature. On its basis, methods have been developed for creating hierarchical mesosubstructures in the [macro-nano] scale range, which greatly increase the low-temperature impact strength and fatigue life of structural materials and eliminate their cold brittleness.
