| Abstract Scope |
Metastable austenite is a key microstructural constituent in advanced steels, and its deformation behavior is strongly related with the stacking fault energy. The stacking fault energy in turn depends on chemical composition and temperature. To better understand deformation behavior of both single-phase austenitic steels and multi-phase steels we have therefore investigated the relation between stacking fault energy, for different alloys and temperatures, and; the microstructure evolution and micromechanics behavior during tensile testing. The main experimental methodology applied is in-situ high-energy x-ray diffraction and this is supplemented with electron microscopy and modelling. We show that the deformation behavior of the austenite in the steels investigated can be rationalized through proper predictions of the stacking fault energy during deformation. |
