Abstract
This present study deals with the hydrogen embrittlement properties of austenitic Fe-30Mn-0.2C(- 1.5Al) high-manganese steels for cryogenic applications. They were electrochemically charged with hydrogen and then subjected to tensile tests for evaluating hydrogen embrittlement behavior. Tensile test results showed that after hydrogen charging the tensile strength and elongation of the Al-free steel were more remarkably decreased with increasing current density when compared to the Al-added steel. After hydrogen charging of the Al-added steel, it was found that the measured hydrogen content was small and silver particles were relatively less decorated. Therefore, the Al-added steel has a superior hydrogen embrittlement resistance to the Al-free steel because the addition of Al suppresses the injection of hydrogen during electrochemical hydrogen charging.
