Studied: (1) features of formation of brazed joints (BJ) of dispersion-strengthened copper alloys (A) and alloys based on Cu with W (adhesion-active braze alloys in different conditions); (2) influence of technological factors on PJ structure and properties. These BJ have passed thermal cycling tests (Timp = 10 s, Tp = 13 s; N = 103); preserved their serviceability after neutron irradiation (5.1021 neutr/cm2, at T = 200 C); (3) features of the processes of interaction on the interphases in heterogeneous systems in flux brazing; (4) microstructure and strength of PJ from dissimilar Me at superlow temperatures. Developed: (1) Mo-graphite brazing technology; (2) arc brazing of graphite-graphite; (3) methods of manufacturing non-corroding fluxes; (4) basic technologies of flux brazing of deformed Al alloys; (5) technology of brazingsteel-Al tubular transition pieces.
