Students are able
• to comprehend the theory behind practical metallography.
• to understand the theory of equilibrium structures of the binary Fe-C diagram.
• to understand the theory of imbalance structures of the binary Fe-C diagram.
• to adjust equilibrium structure and imbalance structure by independently carrying out the end quenching test in tempered steels (C45, 42CrMoS4) and metallographically characterize them, and to do destructive material tests (tensile test, notched bar impact test, hardness test) on metallic structural materials independently.
