The lattice imaging technique of high-resolution electron microscopy has been applied to study spinodal decomposition in a Cu--Ni--Cr alloy. The reliability of various methods for processing the image data is discussed. The important parameters describing a spinodal microstructure (viz, composition amplitude, wavelength of modulations, and relative volume fractions of the two phases) can all be obtained from the lattice image, even though the maximum change of lattice parameters between the two phases is only approx. 1%. Interesting interfacial microstructural features have also been revealed from microoptical diffractograms of the images during later stages of aging.
