The relation between ductility and stacking fault energies in Mg and Mg–Y alloys
Stefanie Sandlöbes,Martin Friák,Stefan Zaefferer,Alexey Dick,Sangbong Yi,Dietmar Letzig,Zongrui Pei,Li-Fang Zhu,Jörg Neugebauer,Dierk Raabe +9 more
TL;DR: In this article, the intrinsic stacking fault I1 energy (I1 SFE) was investigated by transmission electron microscopy and density functional theory, and the influence of the SFE on the relative activation of different competing deformation mechanisms (basal, prismatic, pyramidal slip) was discussed.

Generation and performance of special quasirandom structures for studying the elastic properties of random alloys: Application to Al-Ti
TL;DR: In this paper, the performance of special-quasirandom structures (SQSss) for the description of elastic properties of random alloys was evaluated and a set of system-independent 32-atom-fcc SQS spanning the entire concentration range was generated and used to determine the elastic constants of binary random substitutional AlTi alloys.

First-principles investigation of the effect of carbon on the stacking fault energy of Fe–C alloys
TL;DR: The intrinsic stacking fault energy (SFE) is a critical parameter that defines the type of plasticity mechanisms in austenitic high-Mn steels as mentioned in this paper, and the authors of this paper have performed ab initio investigations to study the effect of interstitial carbon atoms on the SFE of face-centred cubic (fcc) Fe-C alloys.

Thermodynamic properties of cementite (Fe3C)
Bengt Hallstedt,Dejan Djurovic,Jörg von Appen,Richard Dronskowski,Alexey Dick,Fritz Körmann,Tilmann Hickel,Jörg Neugebauer +7 more
TL;DR: In this paper, the Gibbs energy of cementite at high temperature (1000-k and above) was calculated using density functional theory and the energy of formation at 0-k was also calculated using ab initio data combined with statistical concepts.

Impact of nanodiffusion on the stacking fault energy in high-strength steels
Tilmann Hickel,Stefanie Sandlöbes,Ross K. W. Marceau,Alexey Dick,Ivan Bleskov,Jörg Neugebauer,Dierk Raabe +6 more
TL;DR: In this article, the role of carbon for the stacking fault energy in high-Mn steels is investigated, and the long-term mechanical properties and characterisation of these materials are discussed.
