Abstract

The Fourier transform of the Helmholtz Free Energy F(k), for composition fluctuations of wave vector k, has been obtained for several ordering alloys above T//c by measuring the absolute X-ray diffuse scattering intensity due to local order, at high temperatures, along lines in reciprocal space. The single crystals examined were Cu//3Au, Cu-23 at pct Au, Cu-18. 5 at pct Au, and CoPt//3. The values obtained are compared to the theory of continuous transformations and it is found that the linear theory is satisfactory but the nearest-neighbor approximation is inadequate.
