Abstract

Abstract Bending tests were performed to clarify the effect of chromium and molybdenum contents of amorphous FeCrMo13P7C alloys on the susceptibility to hydrogen embrittlement in deaerated solutions of different pH at 40°C. Some alloys suffered hydrogen embrittlement in deaerated 1 M HCl, 1 M NaCl and deionized water. The addition of sufficient sound amounts of both the elements improved the corrosion resistance and resulted in immunity to the embrittlement due to spontaneous passivation. The increase in pH also decreased the susceptibility to hydrogen embrittlement.
