An approximate method is proposed to calculate the pole figure diagrams based on the elastic anisotropy measured by ultrasonic velocity experiments. An example is taken from the surface texture of rolled plates of aluminum alloy 7075-T651, for which the angular dependence of the Rayleigh wave is measured in the rolling plane and analyzed to obtain the expansion coefficients of orientation distribution function. The ultrasonic pole figures are favorably compared with the conventional x-ray pole figures, both demonstrating a single texture centered over (001)[110] orientation.
