| Description
| - The paper describes effect of hydrogen on mechanical properties and fracture characteristics of two variants of the TRIP 800 steels; C-Mn-Si variant and C-Mn-Si-Al variant. TRIP steels are very promising materials thanks to their combination of a very good strength and toughness. However, these steels can be embrittled by hydrogen during technological operations related to hot dip galvanizing. That is why the knowledge of effects of hydrogen on the properties and fracture characteristics of the TRIP steels is of particular importance. In the presented study, effects of hydrogen were studied by tensile tests at simultaneous electrolytical hydrogen charging. Special cells were used for this kind of testing. Electrolytical hydrogen charging was performed in diluted solutions of sulfuric acid. In some cases, potassium thiocyanate was added to the solution to promote hydrogen absorption. Hydrogen provoked embrittlement in both steel variants and changed their micromechanism of failure. The manifestations were different to those observed earlier if tensile tests were performed on specimens charged previously by hydrogen. Hydrogen embrittlement manifested itself mainly by a loss of plasticity. Index of hydrogen embrittlement, expressed on the base of a relative drop of elongation to fracture, reached values between 65 and 85 %. No significant difference was observed between two steel variants studied. Concerning fractographic characteristics, steels containing higher hydrogen content displayed transgranular cleavage fracture in the centre of the fracture area and quasi-cleavage fracture at the borders of the fracture area. The cracks always initiated at the specimen borders at the presence of hydrogen.
