Revealing interstitial energetics in Ti-23Nb-0.7Ta-2Zr gum metal base alloy via universal machine learning interatomic potentials

This study demonstrates that universal machine-learning interatomic potentials can efficiently and accurately map the energetics and site preferences of light interstitial elements (C, N, O, H) in a complex Ti-23Nb-0.7Ta-2Zr gum metal alloy, revealing that local Ti-rich environments stabilize these defects while Nb proximity destabilizes them, all at a fraction of the computational cost of density functional theory.
