TL;DR: It is shown that plasticity in perfect crystals can be triggered by electronic instabilities at finite strains and the ideal strength in transition metal carbides and nitrides is limited by the elastic instability.
Abstract: The ideal shear strength of transition metal carbides and nitrides is calculated with the use of the ab initio pseudopotential density functional method. The microscopic mechanism that limits the ideal strength is studied using full atomic and structural relaxation and the results of electronic structure calculations. It is shown that plasticity in perfect crystals can be triggered by electronic instabilities at finite strains. Our study explicitly demonstrates that the ideal strength in these materials is limited by the elastic instability which is in turn initiated by electronic instabilities. The potential application of alloy hardening due to the onset of instabilities at different strains is also discussed.

TL;DR: Continuum dislocation dynamics (CDD) with a novel constitutive law based on dislocation density evolution mechanisms was developed to investigate the deformation behaviors of single crystals as mentioned in this paper, which is a mechanism-based model with parameters predicted by lower-length scale models or measured from experiments, not an empirical law with parameters back-fitted from the flow curves.
