摘要：

Order in gamma-phase TiAl alloys is investigated by convergent beam diffraction of 200 keV electrons. The separation of different branches of the dispersion surface, as observed in quantum state rings in beams from higher order Laue zones, is shown to provide a direct measure of order. Theory and experiment are shown to be in good agreement.
