DETERMINATION OF THE TOTAL TEXTURE FUNCTION FROM INDIVIDUAL ORIENTATIONS MODELED BY A LORENTZIAN DISTRIBUTION

The technique of individual orientation measurement allows the calcula tion a total texture function by the harmonic method. However, it is n ecessary to test some of the parameters used to model each orientation . One important parameter is the shape of the function so the influenc e of two distributions (Gaussian and Lorentzian) is discussed. With ad justment of some other parameters, such as p, which characterizes the texture sharpness, it appears that similar results are obtained with t he two models even if the Lorentzian function is more difficult to app ly to polycrystalline materials.
