Abstract

The investigations presented in this paper are done within the scope of the Collaborative Research Centre 675 "Creation of high strength metallic structures and joints by setting up scaled local material properties". The production of massive forming components made of metastable austenitic steels with local strengthening by means of forming-induced α-martensite is examined. The aim is the forming-induced setting of high-strength martensitic areas beside ductile austenitic regions for the realisation of locally load-adapted components. Different forming processes were performed for the basic determination of the dependence of the phase transformation on the forming parameters. It was found out that the forming-induced martensite formation essentially depends on the degree of deformation and the forming temperature. The phase transition during the forging process could be influenced by locally different degrees of deformation as well as a temperature difference between tool and specimen. Especially temperatures below ambient temperature increased the phase transformation.
