Small-angle X-ray scattering technique was used to study nano-sized particles of omega phase in single crystals of metastable beta-Ti alloys. The measurement was done on a series of aged samples as well as in-situ during heating. Obtained scattering patterns were described by a short-range order model and it was determined that the omega phase particles are spontaneously ordered in a cubic array along <100> directions in the beta matrix. The ordering was explained in terms of elastic interaction between the omega particles. The evolution of particle size and mean distance between particles was calculated from the fit.
