Information × Registration Number 0216U003982, 0115U003131 , R & D reports Title Influence of nanoscale inoculas on weld metal microstructure development of HSLA steels popup.stage_title Head Yermolenko Dmytro Yuriyovich, Registration Date 07-04-2016 Organization E.O. Paton Electric Welding Institute of the National Academy of Sciences of Ukraine popup.description2 Method of the weld metal microstructure and its mechanical properties improving, doesn't foresee significant changes in the technology of welding materials and welding technology, welding is carried out as required by ISO standard ISO 15792-1:2007. Based on a mathematical model describing the formation of the dendritic structure in the presence of refractory inoculants in the weld pool developed software copyright and conducted calculations that showed that the introduction of a small amount of inoculant significantly affect the kinetics of the primary structure of the weld metal and its morphology. Metallographic studies showed that depending on the type entered inoculants can get various microstructural composition. The study of mechanical properties showed that by introducing refractory inoculants can significantly increase resistance to brittle fracture weld metal. Received a patent UA 102527 U.
