Information × Registration Number 0207U000010, 0103U005426 , R & D reports Title The investigation of influence of the peculiarities of the phase- structural transformations and thermal cycles of welding of the butt joints of a highstrength alloyed steels on their cold resistation and strength. popup.stage_title Head Poznaykov Valeryi D., Доктор технічних наук Registration Date 03-01-2007 Organization E.O. Paton Electric Welding Institute of the National Academy of Sciences of Ukraine popup.description2 Specifics of effect of thermo deformational cycle on formation of structure and properties of joints of highstrength alloyed steels with 0,10-0,40%. C content was studied oft was established that under the action of stresses the structure components are refined and densities of dislocations in a hardened metal are increased. This causes the increase in strength by 20-30% and decrease in ductile properties of HAZ metal by 10-15%, thus leading to the increase in susceptibility of highstrength steel joints to delayed and brittle fracture.
