This month I've started analyzing the data from EBSD measurements which involved preparing maps charts, textures and pole figures from crystallographic data. Unfortunately after consultations with colleagues from AGH it seems that much of obtained microstructural data is strongly affected by sample preparation, therefore big part of investigations will have to be repeated. Apparently fine crystals that are appearing in microstructure are effects of recrystallization that happens after mechanical preparation of zinc surface. Zinc in low temperatures deforms easily by twinning, after the deformation twin boundaries becomes nucleation sites during crystallization which in zinc can occur in room temperature. This process can take place during the preparation thus (deformation during cutting and grinding and recrystallization before surface is polisched sufficiently to observe microstructure) it is difficult to determine wether observed microstructure is real or just result of aggressive preparation.
