“…Various algorithms for implementing discrete methods have been developed during the last decades. For instance, the Vector Method [17] performs direct inversion of the matrix by introducing geometry constraints on the grids. Other methods, such as WIMV [18] or ADC [19] algorithms, first make an initial estimate of the ODF which is used to compute the corresponding initial pole figures.…”

Abstract. In material science, crystallographic texture is an important microstructural parameter which directly determines the anisotropy degree of most physical properties of a polycrystalline material at the macro scale. Its characterization is thus of fundamental and applied importance, and should ideally be performed prior to any physical property measurement or modeling. Neutron diffraction is a tool of choice for characterizing crystallographic textures: its main advantages over other existing techniques, and especially over the X-ray diffraction techniques, are due to the low neutron absorption by most elements. The obtained information is representative of a large number of grains, leading to a better accuracy of the statistical description of texture.

“…In the present paper, the procedure is described, which allows calculating orientation distribution function (ODF) for a single deformed grain using direct pole figures determined experimentally. Our approach is similar to the vector method used by Ruer and Baro for the macroscopic textures [3]. Principal peculiarities of the developed procedure result from the fact that the orientation distribution is examined not on the macroscopic scale but within single grains.…”

The method is described which enables to determine the microtexture that is the orientation distribution within individual grains of a polycrystal. The microtexture is evaluated on the base of X-ray pole distributions measured for separate reflections, referred to as microscopic pole figures (MPF). The procedure for treatment of experimental MPF and the following computation of orientation distribution function is described in detail. Precision of the microtexture evaluation and possible ways of its improvement are discussed. As an example of the method application, orientation distribution within a single grain of aluminum polycrystal deformed by uniaxial compression up to 50% has been examined.

“…The WIMV (Williams-Imhof-Matthies-Vinel) method, introduced by Matthies and Vinel (1982), is most widely used. Variants are the vector method (Ruer and Baro 1977), ADC (Arbitrarily Defined Cells) (Pawlik et al 1991), and the maximum entropy method (Liang et al 1988, Schaeben 1988). Other methods work in Fourier space, most notably the harmonic method introduced by Bunge (1965) and Roe (1965).…”
