HYDROGEN EMBRITTLEMENT OF DUPLEX STEEL 22/05
Original language description
The presented paper evaluates hydrogen embrittlement of a duplex steel 22/05 with ferritic-austenitic microstructure. Tensile specimens with diameter d0 = 4 mm were electrolytically hydrogen charged in 0.1 N solution of H2SO4, without or with addition of1 g of KSCN per 1 liter of solution, for 24 hours or 168 hours. The current density for hydrogen charging varied from i = 1 to 5 mA.cm-2. Tensile tests with low strain rate were performed immediately after hydrogen charging. Impact of hydrogen on mechanical properties of the duplex steel during tensile test was confirmed by decreasing of plastic properties, especially reduction in area. Degree of embrittlement was expressed by the index of hydrogen embrittlement F. Hydrogen charging at current densityi = 1 mA.cm-2 caused almost none embrittlement of the steel studied, index of hydrogen embrittlement F = 0.8 %. Some decreasing of reduction in area was observed for increased current density 5 mA.cm-2, but the index of hydrogen embrittle
