Laboratory for Metallic materials with spatial gradient structure

• We have studied influence of thermal load and various environments on pentagonal objects. For theoretical description of behavior of such objects in force and temperature fields apart from the disclination approach gradient mechanics was also used.
• Our team has solved the elastic problem of dilational inclusion in the form of a cut spherical segment in a spherical particle. On this basis, elastic fields and energy of Janus particles have been determined.
• We have studied evolution of defect structure in pentagonal particles. In addition to the existing models we have proposed a theoretical model describing initial tense condition in dodecahedral small particle as in an elastic sphere with axial partial Wedge disclination and relaxation of this tense state by formation of circular prismatic disclination loops in the equatorial plane of the sphere that is normal to the dislocation line.
• We have have developed and examined materials in the forms whiskers and nano-tapes. Our researchers have shown potential for usage of such materials in Li-Ion batteries.

- The laboratory has conducted the internship «Modeling and quantitative analysis of conditions of crystallization and technologies of growing using the method of electrodeposition of specific nanoobjects» for professionals from research institutions

- The leading scientist has developed the lecture course «Continuum Mechanics and Diffusion»

- One candidate dissertation has been defended
