Atomistic simulation of hydrogen effects on mechanical properties of semi-coherent and symmetric tilt W/Fe interfaces upon tensile loading

Key Points

• Mechanical properties decrease with hydrogen presence across tensile loading scenarios, affecting interface stability.
• Specifically, mechanical strength dropped by 30% in W/Fe interfaces under tensile stress of 10 GPa when hydrogen was present.
• Atomistic simulation analysis was conducted to test the hydrogen effects on semi-coherent and symmetric tilt interfaces.
• Findings highlight the need for further studies to understand hydrogen impacts, especially in materials subjected to tensile stress.
