Nanocrystalline and ultrafine grained materials

Nanocrystalline and ultrafine grained materials are a new class of structural and functional materials characterized by a polycrystalline structure with a grain size of hundreds of nanometers (ultrafine grained materials) or tens of nanometers (nanocrystalline materials).

Owing to extremely small grain sizes, they exhibit very high strength at ambient temperatures and the ability of superplastic flow at high strain rates at elevated temperatures.

Research activities

  • Understanding the mechanism of grain refinement and the formation of ultrafine grained structure by various processes of severe plastic deformation;
  • Understanding the relationship between the structure and mechanical properties of ultrafine grained materials;
  • Uniformity of the microstructure and properties in micro- and macro-scale;
  • Superplasticity and ability of deep drawing manufacturing;
  • Characteristics of grain boundaries and their influence on the properties of ultrafine grained and nanocrystalline materials;
  • Precipitation processes in ultrafine grained and nanocrystalline structures, the role of structural defects, in particular grain boundary types, in these processes;
  • Diffusion processes in ultrafine grained and nanocrystalline materials, formation of diffusion layers, phase transitions;
  • Benign joining of ultrafine grained and nanocrystalline materials allowing to preserve their refined structure:
  • Friction stir welding;
  • Phenomenon of melting point depression in nanomultilayer systems and its application in low temperature joining processes;
  • The performance of ultrafine grained and nanocrystalline materials – i.e. corrosion resistance, electrical conductivity, wear resistance, biocompatibility;
  • Ferritic and austenitic steels reinforced with nano-oxides for thermonuclear and nuclear power applications;
  • Synthesis of metal matrix composites by means of severe plastic deformation methods.

Research offer

  • Investigation of the microstructure on a micro-, nano- and atomic scale by means of electron microscopy techniques;
  • Corrosion tests.
