THE INFLUENCE OF MICROSTRUCTURE ON HYDROGEN DIFFUSION IN DUAL PHASE STEEL
Abstract
The permeation experiments in this study have shown that electrochemical corrosion of dual phase steel in 2M H2SO4 results in hydrogen evolution and absorption of H-atoms in the material. The consequence of hydrogen is special type of degradation known as hydrogen embrittlement (HE). High susceptibility to HE depends on different microconstituents acting as H-traps. The values of diffusion coefficient and H-solubility obtained in this study have shown that transport of diffusible hydrogen can be related to the traps present in DP steel. The metallographic and SEM analyses have revealed only small globular inclusions, acting as reversible traps in ferrite-martensite matrix.
