Summary This paper considers the various methods available for the measurement of small values of in‐situ lattice misfit between a coherent particle and the matrix. Examination of such misfits by Asby‐Brown contrast imaging, moiré fringe measurements, lattice fringe imaging and convergent beam electron diffraction (C.B.E.D.) is considered, and the results obtained by these techniques are compared. In addition the nature of the strain fields in the matrix adjacent to a coherent misfitting particle is examined using C.B.E.D.
