Abstract
This paper outlines a straightforward method that can be used to predict the total number of orientation relationships between a pair of lattices that can be related by an invariant plane strain transformation and the shape change associated with each of the orientation relationships. This paper also provides a simple technique for calculating the shape strain and crystallography directly from electron diffraction patterns or Fourier-transformed digital patterns of high-resolution transmission electron microscopy images. It demonstrates that many of those diffusional phase transformations that are traditionally classified as non-displacive exhibit in fact a remarkable shape change and that the shape change can even be a simple shear.
