I participated in 'The 41th School of Materials Science and Engineering' in 24-27.09.2013 in Krynica (Poland). The conference was organized by AGH University of Science and Technology. The scope of the conference covered fields of materials science such as: iron-based alloys, non-ferrous alloys, surface engineering, welding engineering, oxidation and corrosion, ceramics, composites and polymers, plastic deformation, functional materials. In this conference around 130 participant were attended.My participation in the 41th school was related to the presentation of research results of AA1050 aluminium alloy and delivered in a 10 minutes presentation titled: ‘ Microstructure and texture evolution during annealing of AA1050 aluminium alloy pre-deformed in ECAP ’.
One of the goal of this conference was integration PhD students involved in the field of ‘Materials Science’.
In the conference papers was published my article (in polish):

OF AA1050 ALUMINIUM ALLOY PRE-DEFORMED IN ECAP
Abstract The main aim of the experiment was to analyze the microstructure and texture evolution during recrystallization of commercial AA1050 aluminum alloy. The samples were processed by ECAP in six passes along route A and then annealed for 1 hour at temperatures ranging from 100°C to 350°C. Studies carried out using scanning electron microscopy equipped with local orientation system and X-ray diffractometer. The obtained results showed that at lower annealing temperatures, the material retains ultra-fine grain structure formed by ECAP. At higher temperatures rapid grain growth appears and transformation of flattened grains into nearly equiaxed was observed. The results showed that obtaining the fine-grained and homogeneous structure of equiaxed grains, is problematic.
