Areas of the research:

Evolution of microstructure, thermal stability, phase composition and thermo-mechanical properties of the chosen multicomponent alloys, amorphous and micro-crystalline, involving melt-quenched nano-crystals.

Phase transformations and thermo-physical and thermo-mechanical properties of the chosen intermetallic phases. The subject directed on investigations of the relations between phase transformations, resulting microstructures and thermo-physical and thermo-mechanical properties of the phases. The investigations includes evolution of the metastable microstructure and it's relation to the phase transformations, especially eutectoid decomposition, in the case of the alloys of the formula Ni3(X,Y,Z), belonging to the continuous phase field in high temperature range and subdued to the eutectoid decomposition into pseudo-binary ordered phases of the Ni3X -Ni3Y-Ni3Z type, revealing also temperature dependence of the thermo-mechanical properties like Young modulus and yield strength.

Calculations and optimization of the multi component systems phase diagrams by the CALPHAD method. Experimental determination of thermodynamic properties of metallic and ceramic systems by electrochemical methods supported by DSC, DTA, EDS and XRD methods of analyses. The calculations and optimization of the phase diagrams by means of the software packages: ThermoCalc version S, Pandat 2013 (optimizer included), PanEngine 7. Simulations of the phase transformations diffusion controlled in alloys with use of the Dictra 23 program. Thermodynamic modeling of the particles size effect on the thermodynamic equilibriums in metallic systems.

Investigation of the thermal and thermo-mechanical properties of alloys and other materials and experimental verification of the phase diagrams. Determination of the temperature ranges and character of the phase transformations, heat capacity, mechanical properties and materials dimensions thermal stability ranges, verification of the characteristic points at the phase diagrams. Investigations of the decomposition and oxidation processes by DSC, TGA and thermo-mechanical analysis (TMA). Microstructure and chemical composition analysis by the scanning electron microscopy (SEM).

Development of micro casting by various induction melting methods: crucible melting, half-levitation (CCLM-cold crucible levitation melting) and levitation melting and by the rapid solidification methods. Includes coarse grain, refinement and amorphous alloys preserving high purity and a wide range of the cooling rates.

New lead-free solder materials and soldering technologies (in cooperation with the DN-1 and DN7 Depts.). Micro structural characteristic and phase composition of the phases formed at the zone of the solder /substrate (SEM,TEM XRD methods) and strength of the interconnection.
