Analysis of misorientation distribution in polycrystalline aluminum sheet by using ODF data

The misorientation distributions in deformed and recrystallized polycrystalline aluminum were calculated and analyzed based on the orientation distribution function (ODF) data. The calculation result was a very good statistical description of the misorientation distribution between neighboring grains. The calculated distributions consist of a random part and a characterized part, of which the characterized part represents the major characteristics of the corresponding misorientation distribution. The representability of calculated misorientation distribution is discussed.
