Learning outcomes:
After successfully completing this course, students will be familiar with the fundamentals of mechanical material behavior and the structure of metals. This will enable them to determine and interpret static material parameters. Students will be able to transfer their knowledge into technical applications.
 
They will be familiar with the formation of alloys and will be able to read and interpret state diagrams, schematically illustrate the microstructural development on the basis of cooling curves and to classify real microstructures. Based on this, students will be able to plot the microstructures in the iron-carbon diagram, as well as explain and illustrate the difference between steels and cast iron materials.
 
They will be able to identify and select the different materials by means of material designation systems.
 
They will be familiar with the procedures involved in annealing processes and will be able to select the most suitable one for the purpose and choose the appropriate parameters.  
 
They will be able to determine material properties after hardening using TTI and cooling diagrams and select suitable tempering treatments.
 
They will be familiar with the different methods of surface hardening and their essential differences in properties and processes.
