Duplex stainless steels (DSSs) are usually used in many industrial applications due to their high mechanical properties, good resistance to pitting corrosion, stress corrosion cracking (SCC) and good weldability. Also, another advantage of DSS, compared with austenitic type is low cost. However, in hydrogen containing environments, hydrogen embrittlement phenomena occur, leading to a degradation of the mechanical properties. For better understanding of the hydrogen embrittlement in duplex stainless steels, it is necessary to characterize the distribution and transport of hydrogen in or between the ferrite and austenite phases. To do this, it is effective to charge the specimens with hydrogen...
