Carbon vacancy network mediated hydrogen trapping at the α-Fe/VC interface

Key Points

• The aim is to understand how carbon vacancies regulate hydrogen ingress at the α-Fe/VC interface.
• Analyzed carbon vacancy networks at the α-Fe/VC interface.
• Evaluated hydrogen trapping mechanisms through experimental methodologies.
• Identified a direct correlation between carbon vacancy presence and hydrogen ingress.
• Demonstrated that regulating carbon vacancies enhances hydrogen trapping efficiency.
