The differential X-ray absorption (DXA) method is applied to the thickness measurement of the two types of intermetallic compound, Ni3(Al, Ti) and TiAl, containing finely dispersed precipitate particles. It is shown that the DXA method is applicable even in the presence of particles with coherent strain fields where it is not possible to use the convergent-beam electron diffraction method. It is proposed that the absorption-free intensity ratio required for the DXA method can be determined using the extrapolation method without knowledge of specimen compositions.
