| 摘 要： | 通过渗氢试样的常温力学性能试验和双悬臂梁试样在高温高压高纯水中的腐蚀试验来研究T225NG钛合金的氢脆行为。研究结果表明:T225NG钛合金在空气和高温高压高纯水的环境下具有良好的抗氢脆性能; T225NG 钛合金的氢脆属于氢化物脆性,这是由于T225NG钛合金中渗入的氢导致氢化物的析出引起的;T225NG钛合金表面氧化膜对它优良的抗氢脆性能起了决定性的作用。

| Abstract: | Through the tests of mechanical properties of charging hydrogen and the corrosion tests in loop water of high temperature and high pressure, hydrogen brittleness of T225NG Ti-alloy was studied. The results show that T225NG Ti-alloy has good property of resisting hydrogen brittleness in atmosphere and in loop water. Hydrogen brittleness of T225NG Ti-alloy is hydride brittleness. This is due to the forming of hydride caused by a large amount of hydrogen dissolved in and oxide film on the surface of T225NG Ti-alloy plays an important role in resisting hydrogen brittleness. |
