After successful completion of the course, students are able to understand the relationships between atomic bonds, crystal structures and the resulting material properties. Particular attention is paid to defects of the crystal structures and how these affect the mechanical and physical properties. (Materials are like people: Defects make them interesting) No ruby without "defects" in its corundum structure. The students will also understand how crystal nuclei form and grow. How the various microstructural phenomena of the materials develop (for example, steel and cast iron are used to explain corresponding phase transformations and the resulting microstructures). The students will also understand that especially the 1-dimensional crystal defects (so-called dislocations) contribute significantly to the special properties of metals.

• Application and Processing of Metal Alloys.

Discussion of case studies and exercises.

The course 308.862 covers mostly the same material as 308.137, and according to the official course list both courses are equivalent.

The course is given in German AND English, please see the following schedule:

Vorlesungstermine!

On Mondays (10:00 - 12:00 am, Freihaus Hörsaal 1), the lecture is given in German.

On Thursdays (8:15 - 09:45 am, Getreidemarkt Radinger Hörsaal), the lecture is given in English. The first lecture will be given on the 3.10.

Written and oral Exam!

Both parts of the exam (written and oral) need to be positive (>50 %.

During the lecture, it is possible to take part on the offered small tests (for which we will use four of the mentioned fridays). These are announced during the lecture. The points obtained will be added to the points of the written exam, if the exam is performed within the same year of study and at least 50% are obtained for the written part. It is not possible to worsen the result of the exam by taking part at the small tests.

The exams, written or oral, are based on the script.

Written part: Mandatory for all students. A written exam is typically structured in 7 subsections (which cover the entire lecture content). Part of any written exam is the iron-carbon diagram, corresponding cooling curves, and the usage of the lever-rule.

Oral part: The oral exam is mandatory if the written part was between 50 and 55%, or if major sections of the written exam were below 50%. Typically, the oral part is 1-3 weeks after the written part. Procedure: 1h per group of 4-5 students (typically in teh BE building 4. floor).
