Advanced multi-functional metallic materials laboratory

About Laboratory

Grant Agreement No.:

14.Z50.31.0039

Project name:

Fabrication and study of advanced multi-functional metallic materials with extremely high density of defects

Name of the institution of higher learning:

Federal State Budgetary Educational Institution of Higher Education "Togliatti State University"

Fields of scientific research:

Materials technology

Project goal:

The goal of the project is creating a new class of advanced multi-functional metallic materials with developed metastable defect structure resulting to persisting spatial-gradient structures (SGS), providing unique mechanical, physical, chemical and biological properties

Key project objectives:

- Development of experimental techniques for fabrication by electrodeposition of a new class of metallic materials in the form of intensely defective microcrystals with pentagonal small particles and SGS, including coatings and bulk components prepared from such particles and microcrystals with controlled SGS;

- Investigation of SGS peculiarities pertaining to the surface morphology and growth mechanisms during electrocrystallization with emphasis on the resulting unique properties of metallic particles and crystals having fivefold symmetry axes and containing a high concentration of crystalline structural defects in the original state, including disclination-type defects;

- Study of the SGS evolution in small particles and in bulk materials prepared from them, in the presence of temperature and mechanical fields, as well as corrosive environments;

- Development of theoretical models of formation and evolution of the SGS during

electrocrystallization, deformation and heat treatment;

- Establishment of structure-surface-property relationships for SGS materials, i.e.

relationships between defect structures and peculiarities of the surface morphology of the new soproduced new materials with their resulting mechanical/physical/chemical properties. Further development of multifunctional materials with desired characteristics from agglomerates of metallic small particles with SGS;

- Identification of possible areas of application for this new class of metallic materials with SGS, and corresponding recommendations for utilizing the so-obtained basic scientific results in the technology/industry innovation areas and real economy sectors;

- Establishment of a world-class research Laboratory on "Metallic materials with spatialgradient structure".
