| Abstract(J) | 一般に，高強度材料では水素脆化割れが課題となる場合がある．本研究では，自動車部品を想定し，せん断端面での水素脆化割れへの変形と残留応力の影響に着目した検討を行った．せん断端面での残留応力を低下させる手法を検討し，その一例として，せん断端面を圧縮することで残留応力が低下することを検証した． Translation |
| Abstract(E) | In general, hydrogen embrittlement cracking can be a concern in high-strength materials. In this study, assuming automotive components as the application, we focused on the influence of deformation and residual stress on hydrogen embrittlement cracking at sheared edges. Our group investigated methods to reduce residual stress at the sheared edge and, as one example, verified that compressing the sheared edge effectively decreases the residual stress. |
