Hydrogen trapping and electrochemical corrosion behavior of V-N microalloyed X80 pipeline steels consisting of acicular ferrite and polygonal ferrite
文献摘要：
Hydrogen trapping behavior of V-N microalloyed X80 pipeline steels was studied by means of hydrogen permeation and hydrogen induced cracking(HIC)tests.In addition,the electrochemical performance of the steels in 3.5 wt.％NaCl solution was investigated.Results indicated that the microstructure of experimental steels mainly consisted of acicular ferrite and polygonal ferrite(PF).When the fraction of PF was 9.1％and 30.4％,hydrogen effective diffusion coefficient was 1.624×10-6 and 3.121×10-6 cm2/s,respectively.The pipeline steels were not susceptible to HIC.Numerous potential hydrogen traps distributed in homogeneous dispersion were conducive to high HIC resistance.With increasing the fraction of PF from 9.1％to 30.4％,the corrosion current density increased from 5.39×10-6 to 9.49×10-6 A cm-2,the corrosion potential decreased from-0.48 to-0.57 V,and the charge transfer resistance decreased from 2301 to 2068Ω cm2,respectively.Increased fraction of PF was disadvantageous for corrosion resistance because of galvanic corrosion.
