| Abstract: | The role of dislocation cellular structures in enhancing the resistance to hydrogen embrittlement (HE) in additive manufactured austenitic stainless steels has been acknowledged, yet its significance remains unexplored systematically in existing literature. To address this gap, the interaction of hydrogen with specimens of metastable 316L austenitic stainless steel (ASS) (with a relatively low amount of Ni (~10 wt.%)) and highly stable Cr21Ni6Mn9N (21-6-9) ASS fabricated by laser powder bed fusion (LPBF) was investigated simultaneously for comparison. The slow-strain-rate tensile (SSRT) properties, together with tensile fracture morphologies and microstructures, were examined both in the presence and absence of hydrogen to evaluate the HE resistance. The results were compared to companion testing conducted on conventionally manufactured (CM) ASS and heat-treated ASS to elucidate the influence of dislocation cellular structures on HE resistance. The findings revealed that the 21-6-9 specimens demonstrated significantly greater HE resistance compared to the 316L specimens due to its outstanding austenite stability determined by chemical composition. While dislocation cellular structures had a strong impact on the HE resistance of 316L ASS, they affected slightly for 21-6-9 ASS, suggesting that the dislocation cellular structures are more pivotal in determining HE resistance for metastable ASSs than for stable ASSs. The mathematical conjecture model for HE resistance of ASSs was proposed. [ABSTRACT FROM AUTHOR] |
