    Mechanisms for mitigating liquid metal embrittlement via surface decarburization in Zn-coated advanced high-strength steels by Hyungkwon Park, Seong Hoon Kim, Jin-Jong Lee, Kyeong-Won Kim, Chang-Hoon Lee, Tejaswin Krishna, Yeong-Do Park, Min-Ho Jang, Min-Seo Park, Seong-Kyung Han, Tae-Ho Lee

    Published 2025-05-01
    “…This study demonstrates that decarburization effectively mitigates LME severity, as revealed by interrupted welding tests and microstructural analysis. Crack reclassification based on morphology shows that non-decarburized steel exhibits fewer but more severe straight-shaped (S-type) cracks (72.17 %), whereas decarburized steel exhibits a greater number of shorter, network-shaped (N-type) cracks (79.87 %). …”
