Inhalte

Lecture and exercises will merge. Based on the fundamentals of the lecture the interpretation of phase diagrams will be developed in collaboration with the students. The students will receive exercises and master copies which will be explicated during the lecture and subsequently solved in cooperation. The main contents of the lecture are • one-, two- and three-component diagrams, • naming the phase rooms, • construction of schematic cooling curves, • calculation of phase contents, • application of the lever principle and the Gibbs law. • Using simplified ternary systems as examples the construction of isothermal- and concentration sections is trained.

Lernziele

The students are introduced to the basics and application methods of phase diagrams. An expanded knowledge of binary phase diagrams is communicated. The students will be able to interpret unknown and complicated binary phase diagrams. They can analyze phase contents and phase reactions during the cooling process of an alloy and can discuss the microstructure. The students learn to interpret elementary unknown ternary phase diagrams. They can evaluate phase contents and phase reactions followed by the construction of isothermal and concentration sections through the three-dimensional system. Using the examples of binary and ternary systems constitution theory and the basics of thermo-dynamic methods will be trained with the aim to understand the construction and practical use of phase diagrams.
