Directions of activity
- Study of the mechanical properties (hardness, Young’s modulus, fracture toughness, yield limit, hardenning, etc.) of a wide range of materials (crystalline, polycrystalline, amorphous, polymeric, composite, ceramic, etc.), both bulk and size-limited, under micro/nanoindentation, micro/nanoscratching and uniaxial extention-compression; correlation of the mechanical properties with other physical ones;
- Investigations of the processes and mechanisms of deformation, which take place under micro/nanoindentation and scratching: dislocation sliding, twinning, rotation, densification, phase transition, etc. and application of this knowledge for the study of different physical parameters and phenomena: anizotropy of hardness and fracture, dislocation mobility, scale effect, etc;
- Influence of different factors, intern (structure, dopants, defects) and extern (load, deformation rate, cyclic deformation, temperature, radiation), on the deformation processes and mechanical behavior of materials in macro-, micro- and nano-volumes;
- Using of the micro/nanoindentation and micro/nanoscratching methods for the obtaining of local modified structural, mechanical, electrical and optical properties in the main matrix of material
