Last month we started investigations of new batch of KoBo deformed zinc along with zinc deformed conventionally. For each method two types of initial material with different history have been used. This way influence of method and type of starting material microstructure on final properties can be investigated and compared. Samples for EBSD were prepared as usual, by mechanical grinding and then mechanicall and electrolyticall polishing.
First sample had lots of twins in its microstructure, therefore we decided to repeat the preparation this time using nitric acid etching to remove layers of deformed grains before the polishing. Remaining samples did not contain any visible twins, so they were investigated in original state.

The FIB gun is working again!
After about 3 months brake I can continue my research. I investigated a series of four YSZ samples this month. Samples differed by the sintering temperature. I am going to check who the grain boundary geometries look like in those sinters. Additionally, I was improving the graphical part of my PhD thesis.

Dear all, this month - in oppostion to previous one - full of progress. I have finished all corriosion experiments with as-cast samples. Morover I had a pleasure to participate in "ECS international crystallography school - introduction to tomography". I have learnt a lot about new programms and hardwere solutions in transmission electron tomography based on diffractions.

Surface phenomena in liquid binary metallic systems is performed using molecular dyanmics and Monte Carlo methods. The influence of surface composition on surface tension is analysed.

In February I continued the study of the corrosion of chosen Zn-Mo coatings on steel using the following techniques: OCP, EIS, LP.
