Convergent‐beam transmission electron diffraction was used to determine the crystallographic orientation of submicron‐sizedA15 structure V3Ga and Nb3Al precipitates formed by solid‐state precipitation from supersaturatedBCCsolutions. In each case the crystallographic orientation relation was (to within an uncertainty of ±5°): [001]A15∥[111]BCC; (100)A15∥(11¯0)BCC. This lattice correspondence is intuitively plausible, since it ensures that the closest packed planes and directions of the precipitate parallel to those of the matrix.
