| Popis: | This study examines the effects of titanium content on hydrogen embrittlement in hot-stamped boron steel, by employing an electrochemical cathodic charging method, slow rate tensile tests, and thermal desorption analyses. With increasing titanium content in hot-stamped boron steel, titanium carbides are precipitated, while the resistance to hydrogen embrittlement improves with a slight reduction in the elongation when stress is applied to the hydrogen-charged specimens. The specimens with a high titanium content exhibit a relatively superior resistance to hydrogen embrittlement due to the presence of small titanium carbide precipitates that act as irreversible hydrogen trap sites with a high binding energy. |
