First-principles study on hydrogen segregation in tungsten grain boundaries and its impact on their mechanical strengths: Uniaxial tensile strain effect

Based on comprehensive first-principles calculations, this study systematically investigates hydrogen (H) segregation behavior at Σ3(112)[110] and Σ5(310)[100] tungsten (W) grain boundaries (GBs) under uniaxial tensile strain, and its consequent impact on GB mechanical strengths. Our results indicat...
