Essay

The thesis is devoted to study of mechanisms and kinetics of structure formation in welded joints on HSLA steels with different strengthening mechanisms. 12KhN2MDTs, 10KhSND and 14KhGNDTs shipbuilding steels with solid solution mechanism of strengthening; 06GBD, 10G2FB and 15KhSATYuD building steels with dispersion mechanism of strengthening, steels for main pipelines Kh70 KP + UO and Kh80 KP + UO with dispersion and grain boundary mechanism of strengthening and high-strength structural steels WELDOX 1300 with "complex" strengthening mechanism were studied.
