New projects granted

Two research projects in the field of press hardening were recently approved by the DFG for the LFT:

• Development of a data-driven method for the process design of thermally assisted forming processes and subsequent component evaluation for press hardening
• In-situ characterization of a locally carburized complex phase steel for the production of semi-finished products with tailored properties

Press hardening has established itself as a manufacturing process for safety-critical components. Further improvements in occupant protection can be achieved through local adjustment of mechanical properties. This requires detailed knowledge of the process influences for precise process design.

An alternative method for adjusting the properties is local carburization of the semi-finished product. In addition to the strength-enhancing effect of the additionally absorbed carbon, it also influences the phase transformation temperatures of the steel. This property has not yet been explored in local carburization. Based on this effect, a greater gradation between carburized and uncarburized areas can be achieved by appropriately adjusting the austenitizing temperature. The overarching goal of the project is therefore to establish a fundamental scientific understanding of the process for this process variant.

We look forward to the results developed within the projects and discussed within the team. This team is currently still looking for additional members. The institute's open positions can be found on the homepage under Career.
