COMPARISON OF X-RAY AND EBSD TEXTURES FOR BACK-ANNEALED Al-Mg ALLOYS

摘要

Despite the large number of single grain orientation data, which can nowadays readily be obtained by standard EBSD measurements, the number of grains encountered is still small compared to the number of grains contributing to conventional X-ray macrotexture analysis. In this paper, we will compare macrotexture results obtained for Al-Mg alloy AA 5005 in the cold-rolled and various back-annealed states. The accuracy of EBSD textures is assessed by way of the statistical parameter p, which represents the relative mean square deviation between two textures. Furthermore, the impact of sampling step size on the statistical significance of EBSD texture results is investigated.
