Learning outcomes of the course unit:
The student will acquire advanced knowledge of metallographic analysis of the content of the subject material science. Obtain knowledge about light and scanning electron microscopy and preparation of samples for metallographic welded joints and fractographic analysis. The student can be able identify different phases and structural formations in welded joints of ferrous and non-ferrous alloys. The student find the relationship between equilibrium diagrams and real macrostructure and microstructure of welded joints. He can be obtained knowledges of the fractographic analysis. Student able to identify the fracture mechanism of welded joints based on morphological characteristics of the different types of fractures. All theoretical knowledge practically verified by the analysis of real welded joints.
Prerequisites and co-requisites: none
