Material science:

• weldability of the advanced aluminium- and magnesium-based structural materials, aluminium-matrix composites and dissimilar materials, when using various processes;
• nature of the welding hot cracks and development of the methods of their prevention in welding the advanced high-strength complex alloys, including aluminium and magnesium alloys with lithium;
• weld pool interaction with gases, development of the methods of the molten metal degassing and evaluation of the influence of the welded joint porosity on their performance;
• structural transformations in the welding zone and solving the problem of producing joints with the strength equal to that of the base metal;

• determination of the characteristics of strength and reliability of welded joints in service and searching for methods of their improvement up to the level of those of the base metal;
• nanotechnologies and nano-structured consumables for joining high-strength alloys, dissimilar and composite materials on aluminium base by fusion and solid-phase processes.
• nanoindentation is testing of physical and mechanical properties by the methods of an indenter continuous indentation, scanning, metallography and topography of the materials’ surface & layers.
