Tailoring multi-level hydrogen trap architecture in low-alloy steel via vibration-assisted forming for enhanced hydrogen embrittlement resistance

Key Points

• Enhanced hydrogen embrittlement resistance is achieved through the innovative design of multi-level hydrogen traps.
• The study reports a reduction in embrittlement reflexivity by approximately 30% when comparing treated and untreated samples.
• Using vibration-assisted forming, the architecture of low-alloy steel is tailored for optimal hydrogen trapping mechanisms.
• These findings highlight the potential for improved structural integrity in applications susceptible to hydrogen-related failures.
