Information × Registration Number 0209U005315, 0106U010485 , R & D reports Title Investigation of nature and behavior of hydrogen induced cracks in weldments of HSLA steels for storage, accumulation and transportation of hydrogen. popup.stage_title Head Pokhodnya Igor K., Registration Date 02-02-2009 Organization E.O.Paton Electric Welding Institute of the National of Sciences of Ukraine popup.description2 The laboratory variant of the device for hydrogen thermodesorption research with opperation management by means of the personal computer has been developed and made. As shown by numerical calculation, at concentration of diffuse hydrogen equal to 2,5-10 sm3/100g, in iron there can be a phenomenon of hydrogen-enhanced localized plasticity. A calculation-experimental methods were put forward to determine parameters of energy traps for hydrogen in weld metal, such as hydrogen trap density and their interaction energy. Influence of the energy trap parameters on diffusion kinetics and redistribution of hydrogen in welded joint was analyzed. Product Description popup.authors popup.nrat_date 2020-04-02 Close
