| Abstract Scope |
To generate a highly efficient use of material resources for formed parts a locally adoption of required strength and integrated functions is advised. By using austenitic steel, the volume fraction of deformation-induced alpha martensite, which has an influence on the strength and the magnetic permeability of the material, is highly dependent on the degree of deformation and the workpiece temperature in the deformation zone. By selective adjustment of the process parameters wall thickness reduction Δs and deformation temperature Td it was possible to produce local restricted areas with an alpha martensite volume from almost negligible to 80 % at the same deformation stage, using a spinning or flow forming process. This way axially graded and locally varying mechanical and sensory properties, e.g. for a magnetic displacement sensor, can be produced. The aim of this ongoing work is a closed loop control of properties by using micromagnetic sensors during spinning processes. |
