After successful completion of the course, students are able to:

• understand the relationships between atomic bonds, crystal structures and the resulting material properties.
• describe the effects of defects in the crystal structure. (Materials are like people: Defects make them interesting) No ruby without "defects" in its corundum structure.
• understand how crystal nuclei form and grow.
• explain the diverse structural phenomena of the materials (using steel and cast iron as examples, we will discuss corresponding phase changes and the resulting microstrutcure).
• to understand that especially the 1-dimensional crystal defects (so-called dislocations) contribute significantly to the specific properties of metals.

• Atomic Structure of Materials;
• The Structure of Crystalline Solids;
• Imperfections in Solids;
• Diffusion;
• Mechanical Properties of Metals;
• Dislocations and Strengthening Mechanisms;
• Phase Diagrams;
• Phase Transformations in Metals: Development Microstructure and Alteration of Mechanical Properties;
• Application and Processing of Metal Alloys.

Discussion of case studies and exercises.

The course is given in German AND English.

During the prolog on Mo. Oct. 3rd (2:00 pm, FH HS1) there will be an information session, in which the course of the lecture as well as the examination will be explained. In addition, the historical development of materials will be briefly presented and the special features of metallic materials (such as combination of toughness and strength) will be explained with examples.

Vorlesungstermine!

On Mondays (14:00 - 16:00 o'clock, as presence lecture at the FH HS1), the lecture is given in German. The first unit will be given on the 1st Monday in October.

On Tuesdays (12:15 - 13:45 am, as a presence lecture in the Vortmann HS), the lecture is given in English.

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 in the offered small tests (about 15 min, immediately before four of the mentioned lecture dates). The exact dates will be announced during the lecture, a week earlier. 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%. From the 3rd examination-entrance onward, an oral examination is always required for a positive assessment. Typically, the oral part is 1-3 weeks after the written part. Procedure: 1h per group of 4-5 students (online or in the BE building 4. floor).

Covid-specific: Written exams are held as attendance exams, if permitted. If not allowed, online exams (via zoom) will take place on the dates indicated. Details will follow a few days before the respective exam dates. In any case, please register in time for the desired dates and consider the conditions given at TUWEL.
