This month I took part in a training concerning use of the new WDS equipment. It seems that it will be useful in my PhD work since some X-ray peaks from elements in samples received from IOD overlap and are impossible to be distinguished by EDS. Rest of the month was spent on practicing use of the WDS.

In February, I focused on improving of my first scientific publication. I wrote about electroeposition of Sn-Zn and Sn-Zn-Mo layers from citrate solutions. I mainly describe the results of voltammetric studies. My paper has been already reviewed. I hope that my publication will be published soon. Then you will be able to know more about my research :)

The goal of my dissertation future will improve the structural properties of magnesium alloys AZ 31 and AZ91, by establishing certain microstructural conditions. The main topic of the paper will examine the impact of thermomechanical strengthening of molded magnesium alloy to improve their properties and processing parameters selection, providing an optimal ratio to improve the mechanical properties of the degree of deformation. This method of treatment is particularly interesting due to the predominant industrial process for producing magnesium alloy by die casting. The elimination of material defects, such as porosity which frequently arise during casting, will extend the use of magnesium alloy for a more responsible construction, for example in the aerospace industry.
In parallel, I dealt with two other issues relating to magnesium alloys. Examination of the previously undescribed magnesium balance of phosphorus will provide information about the suitability of this alloy additive. Planned are also trying to strengthen magnesium alloys - Lithium possible intermetallic phases with magnesium and phosphorus.
Another issue concerning the improvement of formability of magnesium alloy molded plastic processing methods, the use of ultrasound in the manufacture of magnesium. Tensile tests carried out so far samples from the simultaneous operation of ultrasound did not cause softening of the material, however, plans to build a position equipped with a head more powerful.
