Using selected area diffraction in transmission electron microscopy, long‐range order in Ni 2 Cr has been clearly detected. Specimens showing order had been aged for 630 h at 500 °C or for four months at 479 °C. The domain size for the specimen aged at 500 °C was about 100 Å, but the domains for the specimen aged at 479 °C were too small to be resolved.
