Property-orientated control of hardening and phase transformation processes during spinning and flow-forming of metastable austenites
Overview
The overarching goal of the entire research project is the realisation of property control within spinning processes. This should enable the locally limited and reproducible adjustment of physical component properties - in an environment characterised by a large number of process parameters and a process sequence that is difficult to predict.
Targeted influencing of phase transformation processes during production should result in high-performance components that have defined graded mechanical (hardness) or ferromagnetic properties and thus offer added value, e.g. with regard to sensory utilisation. Very high demands are placed on the local resolution of the grading, but also on the dimensional and shape accuracy as well as the surface quality, while at the same time high productivity, safety and flexibility of production are required. Within the spinning process, controlled process management of the temperature and degree of deformation parameters should create locally limited fields that fulfil a given property profile as accurately and reproducibly as possible.
