| Abstract(J) | 近年の自動車軽量化・衝突安全性向上の要求により，高強度鋼板の適用が拡大している．高強度鋼板は水素脆化の解決が信頼性における重要課題の一つであり，適切な評価手法の確立が求められる．本研究では国内外で用いられる4点曲げ試験とU字曲げ試験で等価な水素脆化評価を実現する手法について報告する． Translation |
| Abstract(E) | The demand for vehicle weight reduction and improved crash safety has led to the increased application of high-strength steel sheets. For high-strength steels, addressing hydrogen embrittlement is one of the critical reliability issues, and the establishment of appropriate evaluation methods is required. This study reports a method to achieve equivalent hydrogen embrittlement evaluation using four-point bending and U-bend tests employed in domestic and international standards. |
