摘要：
In this paper, three different microalloyed steels were designed to investigate the effect of V on hydrogen trapping and diffusion in mooring chain steel by electrochemical hydrogen permeation technique and Atom Probe Tomography (APT). According to the results, the addition of V in mooring chain steel can decrease the hydrogen diffusion coefficient, and the calculated activation energy for hydrogen revealed that vanadium carbide nanoparticles in steel can trap hydrogen effectively.
