Scientific fields

The areas of scientific interest are currently centred on the advanced fabrication and characterization of nanostructured materials, as well as the mechanical and thermal condutivity characterizations.

Research topics

Current research topics include:

  • Production, characterization and plasma irradiation of metal-carbon nanocomposites;
  • Nanostructure characterization of mechanically alloyed Cu-based, Ni-based, and W-based alloys. Evaluation of their thermal condutivity and wear resistance;
  • Consolidation and further characterization of the mechanically alloyed nanocomposites;
  • Identification and characterization of planar defects and magnetic domains in ThMn12-type of compounds (YFe11Mo, YFe11Ti, NdFe11Mo, NdFe11Ti); Evaluation of magnetic domain configurations in these intermetallics by atomic force microscopy;

Former research topics include:

  • Nanostructure and microstructure characterization of mechanically alloyed materials;
  • Processing and characterization of magnetic nanostructure of permanent magnets;
  • Ultra-fine discontinuous precipitation mechanisms and wear resistance enhancement;
  • Crystalline defects in intermetallic compounds;
