Abstract

Within the Collaborative Research Centre SFB 570 distortion is treated as a system attribute. This means that it has to be investigated during the entire processing of a component. Simulation is a powerful tool to predict and to take action on reducing distortion, but reliable materials data are one of the limiting factors of these simulations.Within these investigation, the material behaviour of the case hardening steel 20MnCr5 is described by thermo physical material values, parameters regarding the transformation and by the stress‐strain curve. Besides the temperature the microstructure has a substantial influence on the deformation curve. The subject of this paper is a description of the stress‐strain behaviour as a function of microstructure in dependence of the temperature and the carbon content by suitable equations. Therefore, tensile tests were carried out regarding different carbon contents for stable microstructures, but also conditions like the metastable austenite.

In literature, only few works are published that make statements on influences between material properties and distortion. There are some investigations on the influence of carbides and their distribution in the structure. Other authors report on a distinct influence of the texture on distortion. Ho
