HYDROGEN INDUCED CRACKING DURING IMPLANT TESTING OF ALLOY STEELS

The initiation and propagation of hydrogen induced cracking in HY-80 and HY-130 steels and E10018 and E14018 weld metals were investigated with metallographic and acoustic emission techniques. The hydrogen-assisted cracking model proposed by Beachem can be employed to explain the changes in both fracture mode and crack growth rate that were observed in the material studied in this investigation. There is a change in the location of hydrogen induced cracking from the base metal in most low-alloy high-strength steels with yield strengths below 100 ksi (698 N/mm**2) to the weld fusion zone in the higher strength HY-130 weldment.
