The field of materials engineering includes the following topics
The mechanical materials testing laboratories are used to analyse material samples to determine their mechanical properties. Materials are tested for strength, ductility, hardness and toughness both at room temperature and under the influence of temperature. In addition, tests can be carried out to determine the fatigue strength in order to evaluate the behaviour of the materials under repeated loading.

The laboratory for non-destructive material testing offers comprehensive analyses of the quality and integrity of materials. In addition to surface crack testing to detect the finest crack formations, the range of services includes the testing of internal defects using modern methods and dilatometry to determine the thermal expansion and transformation properties of materials. Materialography includes the careful preparation of samples and the creation of micrographs to visualise material structures. Subsequent characterisation provides important insights into the structure, properties and quality of the materials.

During heat treatment, materials are specifically heated and cooled to change their properties. Precise temperature control is made possible with the help of chamber furnaces and various quenching media. This allows hardness, strength and toughness to be adjusted and adapted to the respective technical requirements.

Materials are analysed in detail in the scanning electron microscopy and computed tomography laboratories. The scanning electron microscope enables high-resolution imaging of surface structures and the analysis of chemical compositions. Computed tomography is used for the non-destructive three-dimensional visualisation of internal structures and defects in materials in the micrometre range.
