MEB_24_A_1.03.WSK (P241-0447, P241-0448) Mechanical Engineering, Bachelor, SO 01.10.2024 , semester 1, mandatory course
Workload:
Workload of student for successfully completing the course. Each ECTS credit represents 30 working hours. These are the combined effort of face-to-face time, post-processing the subject of the lecture, exercises and preparation for the exam.

The total workload is distributed on the semester (01.04.-30.09. during the summer term, 01.10.-31.03. during the winter term).
75 class hours (= 56.25 clock hours) over a 15-week period.
The total student study time is 150 hours (equivalent to 5 ECTS credits).
There are therefore 93.75 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):
None.
Recommended as prerequisite for:
Module coordinator:
Prof. Dr. Moritz Habschied
Lecturer:
Prof. Dr. Moritz Habschied

Learning outcomes:
After successfully completing this course, students will be familiar with the tensile test, hardness test methods and the charpy impact test and will be able to determine and interpret the corresponding characteristic values. They will be able to attribute specific material behavior to the respective microstructure. Students will be familiar with the basics of elastic and plastic deformation, the microstructure of metals and basic mechanisms for increasing strength. They can correlate these with the material entanglement observed. Students will be familiar with the basic types of phase diagrams in binary systems, as well as the iron-cementite diagram and the connection to cooling curves. They will be able to derive the evolution of a microstructure and correlate it with real structures. They will be able to calculate proportions and phases depending on the concentration. They will be able to select the annealing and hardening processes for steels required to achieve desired properties. They will also be able to select suitable surface hardening methods. Students will be able to determine the microstructure of steel structures. In practical exercises, they will learn to work in teams to acquire new knowledge and to work on interdisciplinary tasks. They will be able to reflect their opinions and defend them with factual arguments.
