TEXTURE DEVELOPMENT IN AL-1.8 WT-PERCENT CU DEPENDING ON THE PRECIPITATION STATE .2. RECRYSTALLIZATION TEXTURES

The development of the recrystallization texture of the alloy Al-1.8 wt% Cu was investigated by analysis of orientation distribution functions (ODF) determined by X-ray diffraction, supported by metallography and EBSD local texture analysis. In dependence on the degree of deformation, the annealing temperature and, in particular, on the precipitation state a large variety of recrystallization textures was found which could be subdivided into four characteristic types. The differences between these recrystallization texture types could be attributed to differences in the nucleation and growth behaviour. From the present results general conclusions about the various recrystallization mechanisms occurring in aluminium alloys can be drawn.
