A normalized unalloyed steel of grade C45E was used as the test material. The specimens were machined from round material with a length of 5,000 mm and a diameter of 20 mm and subsequently polished to a roughness value of Rz < 6 µm. The chemical composition according to the manufacturer's specifications corresponds to the specified limit value
During heat treatment, the unalloyed C45E was austenitized at T = 850°C and then cooled to RT in a controlled manner, resulting in a predominantly ferritic-pearlitic microstructure with a Vickers hardness of HV10 = 216 [4,5]. In the tensile test, the material reached a maximum strength of Rm = 710 MPa and exhibited a yield strength of Rp0.2
Experimental setup and material
The stress-controlled single-stage tests were carried out on a Shimadzu type EHF-U servo-hydraulic test system with a maximum load of 50 kN, a frequency of f = 5 Hz, a sinusoidal load-time function, and a load ratio of R = -1 at room temperature with RT = 25°C.
The specimens were stressed to failure or to reach th
Expansion of the range of courses offered
If a course of study is pursued while the student is in employment, the structure and schedule of the course must differ from the traditional on-campus study module with lectures planned during the week. Here, you can gain an insight into what these differences are.
How is the course structured and what can I expect from a part-time course of study for professionals?
The course consists of self-learning phases and on-campus study phases. At the start of the semester, you will be sent all of the necessary study materials by mail. They will also be made available online. Please work on these independently a
What’s the difference between a part-time course and a “normal” course, and what are the advantages?
With this kind of course of study, you can pursue both a career and an education at the same time. This requires a lot of organization and discipline in order to be able to do both successfully. You can plan your time for yourself, and - apart

Exmatriculation
Exmatriculation terminates your relationship with the HS Kaiserslautern as a student. Your enrollment will effectively be cancelled. In some cases, you may be automatically (ex officio) exmatriculated, for example if you do not pay your semester fee or if you complete your degree course. The exmatriculation is always done
