Modern high strength steels exhibit a structural complexity down to the atomic scale, employ a wide variety of active deformation mechanisms such as twinning or phase transformations and require a processing that provides control down to the nanoscale. This complexity makes it often impossible to identify and describe the relevant mechanisms and structures solely on an experimental basis. Ab initio simulation techniques based on quantum mechanical approaches are ideally suited to provide the missing data on the atomistic and nanoscale but face the challenge that a brute force description of the complexity is often computationally too expensive and thus not feasible. The talk will discuss how new formulations and approaches allow to address this complexity but will also elucidate on questions where the present approaches are insufficient.
