The orientation distribution function (ODF) calculated from measured pole figures with series expansion method is decomposed into texture components of Gauss type distribution and the volume fraction of texture components can be calculated with the model distribution function. Firstly, as fiber texture components are often found in magnesium alloy, the series expansion coefficients for Gauss type fiber components are derived. Secondly, as the textures of magnesium is very complicated, the group decomposing method, i.e., a major component accompanied by several minor components with trivial misorientation from the major one, is proposed to ensure better fitting or decomposing results. Finally, the group decomposing method is used to calculate the texture volume fraction of two typical experimental ODFs.
