1. 1

   CLO 1: This subject aims to teach students advanced instrumental analysis methods to determine the microstructure and phase composition of materials. students will learn to focus only on interlayers and specific phases between material pairs, avoiding large-scale outliers in the analysis of various hybrid composites. the interpretation of the research results, especially the visual and structural analysis of complex phases such as ferrobronze, will be a special focus. finally, students will gain the ability to directly relate the obtained physicochemical parameters to thermodynamic processes.
