Abstract
Transmission electron images of extrinsic‐intrinsic fault pairs in a Fe–Cr–Ni 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.This publication has 9 references indexed in Scilit:
