Atomic-Scale Stress Delocalization Enabled by Local Chemical Heterogeneity Modulates Brittle-to-Ductile Transition in BCC Multi-Principal Element Alloys

Body-centered cubic (BCC) metals often exhibit limited ductility at finite temperatures, and elemental synergy in multi-principal element alloys (MPEAs) offers a promising route to overcome this limitation. Here, we employ atomistic simulations with a high fidelity machine-learning potential—which outperforms traditi...
