The labortatories of the institute of material science dispose of a modern device equipment which allows to examine the quasi-static and cyclic properties of different materials and material states. For quasi-static loads universal test machines, for cyclic loads mechanical and servo-hydraulic machines are used. A superposition with chemical and tribological loads is possible.

Regarding the investigation of chemical and tribological properties of materials suitable corrosion, sliding wear, fretting, fretting-fatique and cavition test stands are available.

A microscopic analysis of materials, material states and fracture surfaces is carried out through light microscopes, which are connected to a modern image processing system. The presentation at higher magnifications is done by scanning electron microscopy with energy dispersive X-ray spectroscopy (EDX) and electron backscatter diffraction (EBSD). For further metallurgical investigations the institute of material science owns a transmission electron microscope with suitable chemical (electrolytic etching) and physical (ion beam etching) specimen preparation.
