In Januar,

New Year has started with application the Miedema and de Boer theory for calculation the formation enthalpies of metallic alloys, for example Fe-Ti. Yielded results was compared with DFT calculation. As is well known, Miedema’s group developed a widely used thermodynamic theory for calculating the formation energies of binary transition metal alloy systems. From first principles, one could calculate the formation energy of any alloy system, however, it is usually very complicated and requires approximations and assumptions in the calculation especially for the ternary and higher component alloys.

In December, I took into consideration issues concerning methods of physico-chemical polyelectrolyte multilayer coatings characterization. I devoted time for a review of the literature on the use of radial flow test to determine the kinetics of cell adhesion on solid surfaces. I also made several attempts to analyze the value of shear stress in the system: blood - material with a modified surface. I also prepared a series of samples for preliminary analysis of FTIR (Fourier Transform Infrared Spectroscopy) and verifying the optimal stiffness of the system for settlement of cells such as smooth muscle and endothelial cells.

Main studies carried out during December:

- analysis of the results obtained so far,
- casting of new quaternary alloy,
- microstructure analysis of prepared ingot using SEM,
- preliminary tensile tests on melt-spun ribbons with molybdenum addition using INSTRON 6025,
- microstructure analysis of melt-spun ribbons with vanadium addition using TEM,
- participation in seminars and lectures

If the title is just 'report', that means that nothing really exciting happened... I have been slowly developing my tools for geometric grain boundary characterization, and collecting ideas for futher work. Hopefully, I should be able to analyze some statistical samples soon. What is more, there appeared the idea of comparing two methods for detecting GB character, as far as I know they have not been confronted yet.

My Research:

-Processing by ECAP (equal channel angular pressing) a sample of AA1050 three times according to route A.
-Completion of series of studies with scanning electron microscopy using technique - EBSD (electron backscatter diffraction) - for creating orientation maps (microstructure) for aluminum alloy AA1050.
-Creating pole figures based on data obtained from orientation maps (from EBSD/SEM measurements).
