Dislocation Dissociation

Transmission electron microscopy (TEM) shows that the dislocation on basal plane (001) of high T c BiSrCaCuO can dissociate into 2 partials of the type [Formula: see text]. The related stacking fault energy is estimated of the order about µb/365 similar to that observed in Cu and implication of this finding has been discussed.

The Impact

AbstractInterstitial alloying has become an important pillar in tuning and improving the materials properties of high-entropy alloys, e.g., enabling interstitial solid-solution hardening and for tuning the stacking fault energies. In this work we performed ab initio calculations to evaluate the impact of interstitial alloying with nitrogen on the fcc–hcp phase stability for the prototypical CrMnFeCoNi alloy. The N solution energies are broadly distributed and reveal a clear correlation with the local environments. We show that N addition stabilizes the fcc phase of CrMnFeCoNi and increases the stacking fault energy.
