  The outstanding mechanical properties of high-manganese steels (HMnS) are a
result of their high strain-hardenability. That is facilitated by strong
suppression of dynamic recovery, predominant planar glide, and the activation
of additional deformation mechanisms, such as transformation-induced plasticity
(TRIP) and twinning-induced plasticity (TWIP). However, depending on the final
application, strongly differing requirements on the mechanical properties of
HMnS are of relevance. In order to design HMnS for specific applications,
multi-scale material simulation under consideration of the processing
conditions that allows for prediction of the final mechanical properties is
required, i.e. strain-hardening engineering based on integrated computational
materials engineering (ICME). In this work, we present an approach that employs
alloy selection by stacking-fault energy calculations, which enables
activation/suppression of specific deformation mechanisms. Tailored
manufacturing, e.g. by thermo-mechanical treatment, severe plastic deformation
or additive manufacturing, provides possibilities to make use of the
strain-hardenability during and after processing to define the mechanical
properties. A computational approach for alloy and process design will be
discussed.
