The effect of small Al2O3 particles (d < 0.1 μm) and of a mixture of Al2O3 particles and SiC-whiskers on the cold-rolling and on the recrystallization texture of aluminium has been studied by neutron diffraction. It has been observed that the strength and the relative intensity of the main rolling components in the deformation texture are affected both by small particles and by introduction of SiC whiskers. In the recrystallized state very different textures have been found ranging from a weak cube texture to a strong {100} <013> (N-texture). The measured textures are related to the size of the recrystallized grains in a discussion of the effect of small particles and whiskers on deformation microstructures and nucleation and growth processes.
