Abstract
The ordering energy for annealed samples of α CuAl is calculated from the experimental coefficients α1 on the basis of the statistical theory for short-range order. The short-range order is studied as a function of the quenching temperature for CuAl alloys containing 11.9, 14.3, 15.9, and 17.6 at.% Al by means of diffuse scattering of x-rays. The experimental temperature dependences of the short-range order coefficient, α1(T), are compared with the theoretical curves.
