Description

The overarching goal of the research project is to establish active property control within metal-spinning processes. This will enable the local, reproducible adjustment of physical component properties in an environment characterised by many interacting process parameters and a scarcely predictable process sequence.

By deliberately influencing phase-transformation processes during manufacture, high-performance components with defined, graded mechanical (hardness) and ferromagnetic properties are to be produced, creating added value—for example, for sensor-integrated applications. This imposes very strict requirements on the spatial resolution of the property gradation as well as on dimensional and shape accuracy and surface quality, while also demanding high productivity, safety and flexibility in production. Within the spinning process, controlled management of temperature and degree of deformation is intended to generate locally confined zones that fulfil the specified property profile as precisely and reproducibly as possible.
