Learning outcomes:
After successfully completing this module, students will be familiar with the principles of mechanical material behavior and be able to apply them to static loads and processes, determine the characteristic values of tensile tests, interpret them and apply them to simple cases by means of laboratory tests.
 
They will be familiar with the composition of microstructures.
 
They will be familiar with the how alloys are formed and will be able to depict them in state diagrams. They will be able to read and interpret state diagrams and schematically depict the microstructural development on the basis of cooling curves and classify real microstructures on the basis of laboratory tests.
 
Students will be able to show the microstructures in an iron-carbon diagram and the difference between steels and cast iron materials.
 
They will be able to work with material designation systems and standardization.
 
Students will be able to select the conditions of a heat treatment in order to adjust the properties for steels and non-ferrous materials on the basis of laboratory tests.
 
Using TTT diagrams, students will be able to evaluate suitable quenching and tempering conditions for steels and evaluate suitable steels.
 
They will be able to select surface hardening processes.
 
They will be able to select the most relevant steels and non-ferrous materials and other materials.
