On 3-4 December 2012, participated in the seminar - Join PhD Seminar - held in Radeburg, Germany.
The organizers of the seminar were: Enano group of the Institute of Materials Science and Engineering at the Technical University of Dresden and the Institute of Metallurgy and Materials Science in Krakow.
The main objective was to present seminars by the participants' own research results, often within the scope of the PhD dissertation of the future, and their discussion in an interdisciplinary group of young scientists.
During the seminar I gave a lecture under the title: Improvement of properties of Mg alloys construction-Importance of Microstructure. The paper presents the evolution of the texture for the basal plane (0001), lateral (10-10) and pyramidal (10-11). In the initial state after extrusion showed a preferential orientation crystallites and increase the degree of distortion caused strong texture. As a result of the manufacturing process of the first basal plane was oriented crystallites {0001} <11-20> direction parallel to the extrusion. At the same time the intensity of the angular range of reflection on the pole figure was broad and vertically stretched, which is clearly visible for the other two planes: prismatic and pyramidal. This vertical scattering intensity maximum corresponds to the direction of extrusion of the sample. Pole figure analysis (0001) of the starting material (0% deformation) showed that the crystal c axis is arranged in the normal direction (ND) and horizontally (TD) with respect to the measured sample. When the value was 28% of the density of crystallites reorientation of raising the density of the underlying planes of the poles {0001} direction ND with respect to the RD. During cold rolling of a grain parallel to the c-axis direction of the activation process of deformation twinning favor the {10-12} planes. Analysis of the images of the microstructure showed that the critical stress for the twinning plane {10-12} is reached already in the first stage of deformation. A further increase in the degree of deformation caused stronger texture {0001} in direction ND, until cracks appear stage. At the same time, the number of twins and increased fragmentation of microstructure occured. There was a trend deviation of basal texture component {0001} about 15 ° from the direction ND to the direction of TD. This deviation could not be used due to sample preparation, which was confirmed by examining the texture on the surface normal to the axis of the tube, as well as on the surface to be analyzed metallography. This type of texture is characteristic of some of the processes forming of magnesium alloys, including extrusion and rolling, where in addition to the base slip, twinning and pyramidal slip, slip increases <c+a> nonbasal activity. Additional studies confirmed the trend deviation texture pole peak (0001) from the radial direction (normal) to the transverse direction. This phenomenon is attributed to the nonbasal slip systems in the hexagonal structure and twinning.
On 5-6 December 2012 we participated in Training - Nano-scale Materials and Advanced Characterization Techniques-held in Dresden, Germany.
Training was organized by the Institute of Fraunhofer in Dresden, supported by FEMS - the Federation of European Materials Societies.
The main objective of training was to broaden the knowledge of participants in the field of nanomaterials and their nanoanalizy, so in the course of lectures delivered by experts in the wider physical and chemical analysis of materials.

Participation in Joint PhD Semianr organized by Fraunhofer Institute in Radenburg/Dresden/Germany on 3-4/12/12. Presentation both theoretical and experimental results. Talk about free atom theory, Bathia -Hargrove and molecular dynamics studies for Al-Zn alloy and experimental activity results for AlZnLi alloys, when two constant ratio Al/Zn were used.
Participation in series lectures related to nanotechniques: Nano-scale Materials and Advanced Characterization Techniques on December 5-6 in Dresen/Germany. Very intersting lectures presenting many possibilities of application experimental techniques for study of the mechanical properties in application to elctronic devices.
EMF measurement for two phase electrode BiLi3. Calculation of the mixed thermodynamic functions and thermodynamic modelling for liquid ternary AlZnLi alloy using Muggianu model and mixed Muggianu with ternary coefficient of Guo.

In December I participated in the conference " Joint PhD seminar, Nano-scale Materials and Advanced Characterisation Techniques" organized by Dresden University of Technology.
During the seminar I presented a speech entitled „Electrodeposition of Zn-Mo and Zn-Sn-Mo layers for corrosion protection of steel”. Also I listened to several presentations by other students from Interstudia Project as well as from TU Dresden. During workshop I listened to several lectures concerning advanced characterization techniques of nanomaterials.

I have collected results obtained for a series of aluminum alloy AA3004. Based on the analisys of EBSD/SEM maps I could draw the following conclusions:
- microstructure of AA3004 alloy subjected to severe plastic deformation (ECAP A6x) and then annealed for 1 hour retain homogeneity up to about 250°C and ultra-fine grain structure. The average grain size below 1 micron is kept up to about 270°C. The most unfavorable microstructure has an alloy annealed at 300°C;
- Number of LAGB and HAGB decreases with increasing annealing temperature which is related to the grain growth. For temperature lower than 300°C, in the microstructure are dominating HAGB and above it their amount is kept constant and the difference between HAGB and LAGB is not as significant;
- The nature of the changes of average dezorientation for HAGB and LAGB as a function of annealing temperature is independent of each other.

In November I spent most of time analyzing results obtained from microbial experiments and AFM measurements. Of course, I was also working in the lab, where I had stained samples after Impact R test and subsequently visualized surfaces by CLSM.I prepared a new series of specimens for HUVEC’s growth kinetics observation but unfortunately cells refused adhesion on my PEM coatings. This failure surprised me a little bit but I figured out reason of tricky behavior of endothelial cells. I didn’t give them any sweets (fibronectin) so they knocked on the other door. ;)
