“…Similar to Mo, Cr facilitates the bainite transformation [24][25][26], may precipitate in complex Cr-rich carbides [27][28][29], and increases solubility of Ti [30,31] and Nb [30,32,33]. In particular, Cr was observed delaying Fe 3 C precipitation in low carbon steel [34].…”

Steel product markets require the rolled stock with further increasing mechanical properties and simultaneously decreasing price. The steel cost can be reduced via decreasing the microalloying elements contents, although this decrease may undermine the mechanical properties. Multi-element microalloying with minor additions is the route to optimise steel composition and keep the properties high. However, this requires deep understanding of mutual effects of elements on each other's performance with respect to the development of microstructure and mechanical properties. This knowledge is insufficient at the moment. In the present work we investigate the microstructure and mechanical properties of bainitic steels microalloyed with Cr, Mo, Nb and V. Comparison of 0.2 wt. % Mo and Cr additions has shown a more pronounced effect of Mo on precipitation than on phase balance. Superior strength of the MoNbV-steel originated from the strong solid solution strengthening effect. Superior ductility of the CrNbV-steel corresponded to the more pronounced precipitation in this steel. Nature of these mechanisms is discussed.

“…Experimental data of several sources are available for solubility products of TiC, however, the steel compositions differ somewhat from the simulations. Gorokhova et al 14 provide solubility products for a steel sample with 14.6 % Cr, 4.6 % Al, 0.4 % Ti and 0.06 % C (there are indications that solubility data refer to atom percent, but this is not entirely clear in the original publication). The solubility products used by Nooning 15 in his thesis are taken from Refs.…”

Atomistic simulations add a new and fundamental dimension to structural design by integrating development, optimization, and life-time predictions of materials with the well established macroscopic simulations based on classical theories. This integration has now become possible due to the availability of advanced computational approaches and atomistic simulation software environments such as MedeA ® combined with ready access to massive compute power. The current capabilities will be illustrated by specific examples including the quantitative prediction of structural and elastic properties as a function of temperature for materials ranging from metallic alloys to thermoset polymers; the precipitation of new phases either for precipitation hardening or as undesired phenomenon leading to embrittlement, for example in Ni-Cr alloys; the effect of alloying elements and impurities on microstructures due to modifications in the strength of grain boundaries; the stress-strain behavior of amorphous boron; the bonding strength of interfaces; and the prediction of transport coefficients including diffusion and thermal conductivity. This contribution will conclude with an analysis of the issues related to the integration of these quantitative atomistic capabilities in the structural design process and it will outline a path forward.
