Registration Date 04-02-2025 Organization E. O. Paton Elektric Welding Institute National Academy of scinces of Ukraine popup.description1 Using methods of modern physical materials science and analytical chemistry to study the distribution and concentration of inclusions, gases and alloying elements, features of structure and structural transformations, kinetics of formation of new phases in alloys (during electrometallurgical processes), in different parts of integral joints obtained by different methods and in powder materials. popup.description2  The correlation between structural and phase changes, mechanical properties and resistance to brittle fracture of the metal of welded joints of structural low-alloy steel S420NL and armor steels Ramor 500, Armox 500 has been established. Technological welding modes have been proposed that will provide structural conditions for obtaining high operational characteristics of welded joints. Mathematical models have been developed and computer simulations of the temperature, stress-strain and structural-phase state of heat-resistant titanium and magnesium MA2-1 alloys were carried out. The obtained data will allow optimizing welding parameters and heat treatment modes to improve the mechanical properties of welded joints. Computer methods of fractal analysis have been developed and applied to parameterize the metal structure of welds of HSLA steels. The feasibility of using fractal parameters for assessing the branching of the boundaries of structural components, viscosity analysis and multifractal analysis has been established.
