title = "Positive and negative effects of hydrogen on tensile behavior in polycrystalline Fe-30Mn-(6 - X)Si-xAl austenitic alloys",
abstract = "We investigated the tensile properties of Fe-30Mn-(6 - x)Si-xAl (in wt.%, x = 0, 2, 3, 6) austenitic alloys precharged with hydrogen gas at 10 MPa. The Fe-30Mn-6Al alloy showed hydrogen-improved elongation through enhancement of work hardening capacity in the plastic instability condition, although the other alloys did not. This improvement in elongation is considered to be a result of a reduction in stacking fault energy because deformation twinning appeared only in the hydrogen-precharged condition.",
