Subject aims expressed by acquired skills and competences
The aim of the course is to deepen the basic knowledge of the student acquired in the previous study in the field of theory of metallurgical processes with a focus on modern directions of development, especially in high-temperature processes.
After completing the course, the student will have deeper knowledge in the field of thermodynamics and kinetics of technological processes with a focus on metallurgy. He will be able to apply the acquired theoretical principles in technological practice.
