The stacking fault energy (SFE) was determined in high-manganese twinning-induced plasticity (TWIP) steels using neutron diffraction. Significant contributions of the deformation-induced stacking faults to the peak position shifts for successive orders of diffraction, in this case (111) and (222), were quantitatively correlated to the stacking fault probability and the SFE. The result shows that the SFE increases considerably from 17 to 37 mJ/m 2 as the Al content increases from 0 to 2 wt.% in the Fe-18Mn-0.6C TWIP alloy system.
