Comparação entre os processos de expansão em série, WIMV e ADC no cálculo das Funções de Distribuição de Orientação Cristalográfica (FDOC) em diferentes intensidades de texturas para um Aço IF

Abstract

In grains present in the structure crystalline of material to own different crystallographic orientation between one and another it, that is can concentrated around into preferential orientation or texture. The texture representation is taking through of pole figure, it is stereographic projection that show the pole distribution or plane normal for a given plane (hkl), using the axis in the sample as reference. The pole figure does not describe the completely texture, so it is necessary to be use a orientation distribution function (ODF) with specify objective the frequency which of crystallographic orientation {hkl}<uvw> occur in the given region. There are some methods used for measure the ODF, being the most widely used the series expansion method and discrete – WINV and ADC methods. In this paper goal comparison the ODF measure by the three methods into IF steel 70% cold rolling and recrystallized condition. Then were used the follow software PopLa®, M-TEX® and Labotex®. The paper discusses suitability in the each method.
