Description
| - Hydrogen embrittlement mechanisms of two very high strength steels (VHSS) with ultimate tensile strength reaching 1000 MPa were studied in severe hydrogen charging conditions. These VHSS were a TRIP steel (A) and a Cr-V alloyed high strength steel (B). They were submitted to cathodic charging in a sulfuric acid solution (0.1 N) with an addition of 5 mg L-1 of As2O3, as a promoter of hydrogen absorption. Electrochemical permeation technique and subsequent hydrogen dosage by thermal desorption tests provided values for hydrogen diffusion characteristics. A and B present diffusivity of respectively 2.6 10-11 m2 s-1 and 2.2 10-10 m2 s-1. Blistering occurred at high charging currents, but residual hydrogen content appeared to be very low for both steels. The results can be attributed to the fine homogeneous microstructures with very few lattice defects like inclusions, impurities or microcracks that are the most potential sites for hydrogen trapping. Otherwise, tensile tests performed on hydrogenated steel
