Study of Hydrogen Embrittlement of the TRIP 800 Steels by Means of Tensile Tests at Simultaneous Hydrogen Charging
Original language 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 performedin 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
