Hydrogen embrittlement in super duplex stainless steels
Materialia, 2019 In super duplex stainless steels (SDSSs), both austenite and ferrite are susceptible to hydrogen embrittlement, however there is a lack of understanding into the effect of hydrogen in each phase. In this study, in neutron diffraction was applied on hydrogen-charged (H-charged) samples to investigate the hydrogen embrittlement behaviour in super duplex ...
