日本語
X80パイプライン鋼の溶接熱影響部（HAZ）の各サブゾーンを模擬した試験片を用い、高圧水素含有石炭ガス環境での水素透過実験を実施。水素拡散係数などの透過パラメータを算出し、X80鋼と比較した。結果、HAZの水素拡散係数はX80鋼より低く、水素脆化感受性が高いことを示唆。水素輸送インフラの安全性評価に重要な知見を提供。
English
This study investigates hydrogen permeation in X80 pipeline steel and its weld heat-affected zone (HAZ) under high-pressure coal gasification environments. Using welding thermal simulation, specimens from different HAZ subzones were tested, revealing lower hydrogen diffusion coefficients in HAZ compared to base steel, indicating higher susceptibility to hydrogen embrittlement. These findings are crucial for assessing the safety and integrity of hydrogen transport infrastructure.

📄 Abstract（原文）
Specimens of different subzones of the heat-affected zone (HAZ) of X80 pipeline steel weld joints were prepared using welding thermal simulation technique, the hydrogen permeation behavior in X80 steel and the HAZ was investigated through hydrogen permeation experiments in a high-pressure hydrogen-containing coal-derived gas environment, and the corresponding hydrogen permeation parameters were calculated. The results revealed that, compared with X80 steel, the hydrogen diffusion coefficient ...
