I have done this month:
- sample preparation to SEM obserwation;
- orientation maps measurment (EBSD/SEM technique) for 3004 and Al-Zr aluminium alloys;
- plane strain compression for the 1050 aluminium alloy in the deformed state (after 0, 1- and 3- passes through ECAP die);
- attendance in PAS Semminars.

This month I was writing the next chapter of my PhD thesis, which in fact is the most important one and concerns the final results of my work.
In the meantime I have tried to finish the last part of experiments connected with the characterization of bulk samples.

During this month I have stared to pepare to very important presentation in my institute. I tried to revised all the data from previous years and conclude them - unfortunately it is not done yet. Moreover, I started corrosion experiments on heat-treated samples.

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.
