Resumen
PALACIOS GOMEZ, J.; SALAT FIGOLS, R.S. y KRYSHTAB, T.. A method to obtain orientation curves in Euler space for a seccond diffraction process in polycrystals. Rev. mex. fis. [online]. 2018, vol.64, n.4, pp.375-380. ISSN 0035-001X.
A method is presented to obtain the orientation curve in the Eulerian space, of crystallites which diffract in one point of a Debye-Scherer ring in a second diffraction process. The incident beam is therefore the reflected beam of a previous diffraction process, and the sample has a general orientation for a pole figure measurement, given as usual by two angles, χ around the sample 𝑌 axis, and 𝜑 around the sample normal. Two solutions are found for all secondary reflections. The method proposed here was outlined somewhere else for the measurement of pole figures by neutron diffraction, and here important improvements are made, especially regarding the mathematical methods.
