Effect of Thermal Processing on the Texture and Microstructure of Aluminium

Abstract

The effect of different heat-treatments on the textural and microscopical development during recrystallization of heavily deformed commercially pure aluminium was studied using in-situ neutron diffraction texture measurements and various microscopical techniques. During annealing the intensity of the cube texture was measured on-line whereby direct information about the textural development was obtained. For the fully recrystallized specimens the complete texture, in the form of a three dimensional orientation distribution function (ODF) was determined and the volume fraction of the main texture components was calculated. It was found that parameters such as annealing temperature and time plus heating rate had a significant effect on the recrystallization texture.
