The purpose of the work - development of scientific bases and technological methods of laser welding of multicomponent heat-resistant alloys for aerospace products Research methods - analysis of physical phenomena that accompany the processes of laser welding of multicomponent heat-resistant alloys and their modeling; visual, non-destructive and destructive methods of control; metallographic research; X-ray diffraction and micro-X-ray spectral analyzes; scanning electron microscopy; microdiurometric analysis; mechanical tests. Based on the results of the work, the links between chemical and phase composition, structure, physical and mechanical properties and laser welding modes of new multicomponent heat-resistant alloys based on Nb-Cr-Ti-Zr-Al and Nb-Cr-Ti-Al-Zr systems were established -Mo-S The scientific results obtained during the research (on thermal processes, behavior of the welding bath, physical and mechanical properties, structure of the obtained welded joints of multicomponent heat-resistant alloys based on niobium, etc.) will be used in the development of technological methods, technological equipment and technological recommendations that will form the basis of the development of industrial technologies for laser welding of welded joints of multicomponent heat-resistant alloys for products of rocket and space technology, nuclear energy, chemical and other industries.
