摘要：

Transmission electron images of extrinsic-intrinsic fault pairs in a FeSingle Bond signCrSingle Bond signNi alloy are shown to be sensitive to changes in the sign of (g·b)s for reflections producing either line or stacking-fault contrast. This is interpreted in terms of the overlapping strain fields of the three closely spaced partial dislocations. A differential treatment of the measured widths of the intrinsic and extrinsic faults indicates that the stacking-fault energy ratio γe/γi=1. 6 in this alloy. © 1969 The American Institute of Physics.
