Predicting Highly Anisotropic Dislocation Core Properties of B2 Alloys Using an Ab Initio-Informed Fully Discrete Peierls–Nabarro Model

An ab initio-informed fully discrete Peierls–Nabarro (FDPN) framework is employed to establish quantitative links among the generalized stacking fault energy (GSFE) landscape, dislocation core structure, and intrinsic lattice resistance in six B2 alloys (NiAl, FeAl, CoAl, RuAl, CoTi, and NiTi). Material-specific elasti...
