The production of spurious lines of intensity in high‐energy electron diffraction patterns by double diffraction between a strong Bragg reflection and a plane of diffuse intensity was demonstrated in a Ti–Nb alloy containing the ω phase. The conclusion that {111} planes of diffuse intensity passing through the reciprocal space origin are absent was shown to be consistent with the presence of 〈111〉 rows of ω particles suspended in a body‐centered cubic matrix.
