1. 1

   CLO 1: Students will learn to analyze the formation mechanisms of complex alloy steels and multi-component advanced alloys with high performance properties. microstructural characteristics of high-entropy alloys ($alcufecrni$, $tizrnbfeco$, etc.) with especially complex phase transitions, as well as their thermodynamic stability, will be deeply investigated. students will be able to scientifically justify the role of specific alloying element concentrations (for example, the specific proportion of copper or titanium in the respective alloys) in the formation of BCC or FCC phases. as a result, the ability to correctly select specific compositions and predict their mechanical properties for complex engineering applications will be developed.
