The completeness of the beta -> omega transformation in omega particles in a Ti-8 at.% Mo (Ti-15 wt% Mo) single crystal was investigated by measuring the X-ray diffraction maximum 20 (2) over bar2, which is forbidden in both the pure body-centred cubic beta phase and the hexagonal omega phase, and also the diffraction maxima 0001, 0002 and 10 (1) over bar1, which are forbidden in the beta phase and allowed in omega. From a comparison of the integrated intensities and widths of the diffraction peaks with simulations, the effective (mean) degree of the transformation was determined and the radial profile of the transformation degree in an omega particle was estimated.
