| 摘 要： | 研究了Ti6Al4V合金在不同置氢温度、保温时间和氢压下的吸氢行为,利用光学显微镜研究了氢在钛合金中的分布规律。研究结果表明,Ti6Al4V合金的氢含量是由置氢温度、保温时间和氢压来控制的。随着置氢温度的升高,氢含量先增加后降低。随着氢压的增加,氢含量直线增加。钛合金的吸氢过程实质上是氢的扩散过程,随着保温时间的增加,合金中的氢分布逐渐趋于一致。

| Abstract: | Hydrogenation behavior of Ti6Al4V alloy was investigated at different hydrogenation temperatures, holding time and hydrogen pressures. Distribution of hydrogen in titanium alloy was studied by OM. Results show that hydrogen content of Ti6Al4V alloy is controlled by hydrogenation temperature, hydrogen pressure and holding time. Hydrogen content increases first and then decreases with the increasing of hydrogenation temperature, increases linearly with the increasing of hydrogen pressure. The process of hydrogenation is a diffusion of hydrogen into titanium alloy, distribution of hydrogen becomes uniform with an increase of holding time. |
