Flow curves
We provide you with customised data preparation and data transfer. We adapt our results to your data interface (FEM). You receive your results compiled in tables in Excel format or, if required, in ASCII format. In addition, the data is clearly presented in diagrams and summarised overviews.
Determined flow curves are corrected for friction and temperature. This means that we provide you with isothermal flow curves without the influence of forming heat and friction during the forming process.

Microstructure development
Material developers have recently become increasingly interested in the microstructure development of materials. Not only the phase transformation but also the material state before the transformation have a major influence on the manufactured product. We have the necessary experience to describe the state of the material. Among other things, we carry out analyses of softening kinetics, austenite grain growth and phase transformation with the support of the metallographic laboratory.
We produce ZTA, ZTU and UZTU diagrams, which form the basis for technology development. Thanks to our unique equipment, we are able to produce technological UZTU diagrams. These show the transformation behaviour of the material after a forming simulation, which can be carried out with a maximum forming degree of 10 (torsion) and/or 1.2 (upsetting).

Material and technology development (experimental simulation)
We are involved in the development of new materials, including for direct use technology. This process requires knowledge of the formability of the materials and methods for influencing the microstructure development.
By simulating reheating and direct application technology, we are able to influence the microstructure and property development of the material with the support of metallography. We are able to realise temperature and forming processes within very wide limits. Mini tensile, impact and microstructure samples can then be taken from a flat upsetting sample after the technology simulation has been completed.

Focus of work
- Expanding the knowledge of material behaviour during and after forming processes
- Continuously adding to and improving the flow curve database (more than 500 entries)
- Training and further education of practice-oriented engineers
- Determining the influence of the initial state of a material on the hardening and softening behaviour (grain size, solution state, phase fractions, degree of purity and other heat-dependent processes)
- Determination of dynamic hardening and softening processes as a function of the forming conditions (temperature, degree of forming, forming speed)
- Determination of static softening processes in pause times between two forming processes and after forming
- Determination of the precipitation kinetics over the entire process chain
- Determination of the transformation behaviour of the material in connection with its forming and thermal history and the cooling strategy
- Determination of mechanical properties after the experimental simulation of different process chains
