Abstract

To investigate the relation between hydrogen content and AE signals, a tempered carbon steel of Type Ck 35 (German DIN standard) was selected. Materials without hydrogen embrittlement show acoustic emission in the second load phase only if the level of the first load is exceeded. Hydrogen embrittled material shows acoustic emission in the second load phase below the level of the first load phase (restrained Kaiser effect).
