Abstract

Excerpt: Using Monte Carlo simulations, we identify the chemical and structural preferences of these interstitials in both bulk and GB environments, aligning with experimental segregation and precipitation trends. ... In support of ongoing hydrogen embrittlement mitigation strategies, we also examined hydrogen behavior.
