- The effect of hydrogen on the tensile behavior of two 18Cr10Mn austenitic steels having the
similar stacking fault energy but different nitrogen and carbon contents was investigated.
The steels were thermally charged with hydrogen at 15 MPa and 300 C. The hydrogen
content was determined using thermal desorption spectroscopy. The microstructure and
fracture surface of the specimens were characterized using X-ray diffraction, optical and
scanning electron microscopy. The ductility loss after hydrogen charging was greater in the
steel with higher nitrogen content. The fracture behavior is discussed in terms of austenite
phase stability and the localization of slip in the presence of nitrogen and hydrogen.
