| Abstract Scope |
Among advanced high-strength steels, high manganese steels have a superior combination of both a high UTS and a large total elongation. As a consequence of plastic deformation, these austenitic steels transform by creating mechanical twins (TWIP) or ε-martensite (TRIP). The deformation products depend significantly on the value of the stacking fault energy (SFE) which is in turn a function of the alloy composition. The objective of this work is to investigate the effect of carbon content and on the mechanical properties of a compositionally graded Fe-22Mn-C alloy. For this purpose, an Fe-22Mn-0.6C steel was decarburized under different atmospheres at 1000 ºC to obtain Fe-22Mn-0.4C and Fe-22Mn-0.2C homogeneous steels. Moreover, one carbon graded Fe-22Mn steel was obtained with a carbon content of 0.2 wt. % at the surface, and 0.6 wt. % at the core. The mechanical behavior and microstructural evolution during deformation of these steels will be discussed. |
