The materials testing group is responsible for the determination of material properties and process boundary values, as well as their preparation for the use in process simulation and material modelling tools. The properties can be determined either directly from the measured data or by a subsequent inverse modelling. A particular focus of the group is the process related characterization of microstructure evolution.
The Materials Modelling group deals with microstructure evolution during thermomechanical processes. This includes modelling and simulation of grain size, texture and precipitation.
In addition to the classic forming processes such as rolling and forging, new process variants such as dry forming and roll cladding are also investigated.
Flat & Long ProductsAhrens+Steinbach Projekte
The group for flat and long products deals with all questions concerning the production of semi-finished products. An emphasis lies on rolling processes such as flat and caliber rolling. For those processes fast online models, new tool concepts and modelling approaches are developed. Thus, new process controls and geometries of the semi-finished products as well as deeper process knowledge become accessible.
The research group strip casting is working on further development of the vertical twin-roll casting of steel. Their research includes further development of the process with regard to quality and new products, enhancement and optimization of caster components and the development of new, for twin-roll casting optimized materials and their processing.
Bulk Metal FormingMartin Braun
The bulk metal forming group studies, by means of processes as e.g. forging and ring rolling, numerous different research topics such as increasing the geometry limits and process optimization. Furthermore, models representing bulk metal forming processes are developed, which can be used for process design, prediction and improvement of workpiece properties as well as training courses.
Sheet Metal FormingThilo Vogel
The Sheet Metal Forming group examines conventional sheet metal forming processes, such as deep drawing and bending, next to innovative processes: the combination of stretch forming and Incremental Sheet Forming is suitable for the economic production of small series. In addition, the Finite Element method is applied to design and optimize sheet metal forming processes numerically.
