用中子衍射法测定了高锰孪晶诱发塑性钢的层错能。变形引起的堆垛层错对连续衍射级的峰位置偏移的重要贡献，在这种情况下，（111）和（222），与堆垛层错概率和SFE定量相关。结果表明，随着Al含量从0增加到2 wt.%，SFE从17增加到37 mJ/m2在Fe-18 Mn-0.6C三元合金体系中，(C)2012爱思唯尔有限公司版权所有。
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. (C) 2012 Elsevier B.V.
