The materials science laboratory is equipped with a notched impact hammer and a device for the Jominy face quenching test, which are basic tools in materials science education.

Particularly, bcc materials tend to have a strongly temperature-dependent strength behaviour, which can be determined in the notched bar impact test. In the temperature range > RT the temperatures could not be reproduced in the laboratory test, which means that an essential aspect of the training in the laboratory test has been lost.

In the future, the furnace is also to be used in the face quenching test according to Jominy. By means of the face quenching test the hardening and tempering behaviour of steel can be investigated. The sample is austenitized and then quenched over the face. The cooling conditions along the sample are a function of the distance to the end face. After complete cooling, a hardness test on the sample surface can be used to determine the location-dependent strength of the material. This test will probably be included in the test plan from the coming semester onwards.

The procurement of a chamber furnace was an essential prerequisite for carrying out both experiments.

The furnace will be used in the materials science laboratory, which is attended by approx. 130 students in the attendance course and approx. 40 students at the BbB.
