Learning outcomes:
After successfully completing this course, students will be familiar with the tensile test, hardness test methods and the charpy impact test and will be able to determine and interpret the corresponding characteristic values. They will be able to attribute specific material behavior to the respective microstructure. Students will be familiar with the basics of elastic and plastic deformation, the microstructure of metals and basic mechanisms for increasing strength. They can correlate these with the material entanglement observed. Students will be familiar with the basic types of phase diagrams in binary systems, as well as iron-cementite diagram and the connection to cooling curves. They will be able to derive the evolution of the microstructure and correlate it with real structures. They will be able to select the annealing and hardening processes to steels required to achieve desired properties. They will also be able to select suitable surface hardening methods. Students will be able to determine the microstructure of steel structures. In practical exercises, they will learn to work in teams to acquire new knowledge and to work on interdisciplinary tasks. They will be able to reflect their opinions and defend them with factual arguments.
