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 w t% Cu was investigated by analysis of orientation distribution functio ns (ODF) determined by X-ray diffraction, supported by metallography a nd EBSD local texture analysis. In dependence on the degree of deforma tion, the annealing temperature and, in particular, on the precipitati on state a large variety of recrystallization textures was found which could be subdivided into four characteristic types. The differences b etween these recrystallization texture types could be attributed to di fferences in the nucleation and growth behaviour. From the present res ults general conclusions about the various recrystallization mechanism s occurring in aluminium alloys can be drawn.
