Our experiments:

• Experiments with constant extension rates (CERT) or constant tension (creep test) in compression and pressure mode (speed: 1 mm/h - 100 mm/min; Maximum load: 100 kN)
• High and low-frequency cycle fatigue measurements (HCF, LCF) in strength or elongation controlled mode (max.: 100 kN/100 cycles per second)
• Crack growth measurements during static and dynamic load - also under the influence f an thmosphere

Our setup parameters:

• Temperatures: -140°C to 600°
• protecting or aggressive gas atmospheres
• Temperatures to 1000° in the three-zone resistance furnace at air; (tension setup only,, LCF, HCF)
• Temperatures to 1400° at air or in inert gas (gas-stream)

We evaluate:

• Yield strength
• Tensile strength
• Elongation at failure
• Change deformation curves
• Cyclic stress strain curves
• Life cycle predictions at cyclic deformation (e.g. Wöhler curves)
• Fracture toughness
• Cyclic stress intensity factor
• Threshold value of the crack growth

We relate:

In order to examine failure mechanisms further investigations on the microstructure are often necessary. We have several analyse methods in-house as e.g. scanning and transmission electron microscopy, X-ray diffraction, etc..

• In our INSTRON reference laboratory DIN standard tests as well as tests with special specifications are executed.
• The analyses of the reasons and circumstances of materials failure represent the heart of our investigations.
• Our knowlegde and long-term experinece with mechanical testings is your benefit.
