FRACTURE BEHAVIOR OF 34CrMo4 STEEL IN HIGH-PRESSURE HYDROGEN ENVIRONMENT
Original language description
The paper summarizes test results of fracture toughness measurement at static loading measured in pure hydrogen environment at pressure 15 MPa. Experiments in hydrogen environment were performed in hydrogen autoclave developed by MATERIAL AND MATERIAL RESEARCH Ltd. Test method was chosen in accordance with ČSN EN ISO 11114-4, method B. Resistivity against unstable fracture or crack growth is measured using stepped increasing of stress intensity factor applied to a specimen. Test process was monitored by potential method. Post-test examination including fracture surface analysis using scanning electron microscope was performed for better understanding of unfavorable effect of hydrogen on crack tip of specimen. Test results confirmed significant change of fracture mechanism in comparison with fracture behavior in the air.
