説明:

(abstract)

• High-pressure hydrogen exposure accelerated crack growth in AISI 304.
• Hydrogen reduced plasticity-induced crack closure, increasing ΔKeff.
• AE initiation occurred earlier after hydrogen charging at all ΔK levels.
• AE clustering revealed hydrogen-suppressed ΔK-dependent crack-tip behavior.
• Martensitic transformation was not directly detectable by AE RMS voltage.
