        In November I performed some microhardness measurements on melt-spun ribbons with different loading rates. I tried to gather data I have obtained so far and analyze them to set research plan for nearest months. In this month three new melt spun ribbons with W, Hf and Nb addition were prepared. Addi

        Continuation of the molecular dynamic simulation for liquid binary alloys Al-Zn, Al-Li using EOPP and MEAM potential for modelling the viscosity, density. Attempt to find the interatomic potential for Zn in order to application for liquid Al-Zn alloy. In case of Al-Li alloy, many variants were used

        Samples polished grit paper the final of 1200, and then polished the diamond pastes (powder with a diameter of 6, 3 and 1 micron). The samples to be further polished for microscopic examination using a colloidal silica having a particle size 0.06 microns, and then digested with the alcohol solution

        During last couple of weeks samples of KoBoed earlier zinc were analyzed by means of EBSD technique in SEM. As pointed before samples were held in liquid nitrogen temperature prior to metallographic preparation and inspection. Crystal Orientation maps from transverse sections revealed microstructure

        In October I performed experiments in order to assess thrombogenicity and lymphocytes activation by alginate and poly-L-lysine modified capsules. This beads could be immobilized on the polyelctrolyte multilayer surface and applied as an effective carriers for various growth factors stimulating HUVEC

        We started to characterize the ribbons containing Al substitution in place of tin by SQUID measurements. These results will allow the study of the magnetic properties of the alloys.

        With respect to the studies carried out in August (AFM and profilometer) additional tests were performed using confocal microscopy. The investigations showed that the sample etched in a solution of 8HF:1HNO3:1H2O volume ratio for 60 seconds was characterized by a normal regular surface microstructur

        Actually I have done nothing spectacular this month. I started to work with two example data sets: yttria and nickel superalloy. I spent a lot of time playing with various parameters that can be set in the software for data clean-up and boundary surface reconstruction. I developed a part of computer

        In October I visited Institute for Technical Physics and Materials Science in Budapest. During my stay I had opportunity to perform in-situ heating on thin foil of the multicomponent alloy (with Zr and Mo addition). In this month I also prepared some new alloys by conventional casting. Cast samples

        In October I decided to change a production route of my in situ Al/AlN composites. As a solid state reaction method hasn’t really worked out, I decided to switch to liquid state reaction (but still with a use of magnesium nitride as a nitrogen-bearing medium).

        I also visited the Institute

        During October I was trying to investigate Al6013 sample. It was processed using the KoBo method. I was trying to collect EDS data along with EBSD. First try was unsuccessful because of unknown software error which resulted in stopping of the experiment. During the second try, a microscope failure o

        The article entitled "Investigation of structures in as-cast alloys from the Mg-Zn-Ca system"
        was sent to Achives of Materials and Metallurgy

        In October I’ve studied the electrodeposition process. I lead the process of potentiostatic deposition of Zn-Mo alloy layers, on the steel and copper surfaces, from stable homogeneous Zn(II)-Sn(II)-Mo(VI) and Zn(II)-Mo(VI) citrate baths, in the slightly acid range (pH about 5), with different concen
