在研究氢对金属的影响时,常需要向金属中充入一定量的氢。而充氢方法和充氢条件是获得研究所需的氢浓度以及使氢在试样中均匀分布的关键。本文研究了钛合金高温气相充氢的方法,它的实验装置和控制方法。利用这一方法可以有效、准确地向钛合金中充入研究所需的一定量的氢。本文还研究了钛合金在高温拉伸试验和超塑性试验中,试样保氢的方法,并介绍了试验装置。
When studying the effect of hydrogen on metals, it is often necessary to fill the metal with a certain amount of hydrogen. Hydrogen charging methods and hydrogen charging conditions are the keys to obtaining the hydrogen concentration required for the study and to distributing the hydrogen evenly throughout the sample. This paper studies the high-temperature gas-phase hydrogenation of titanium alloy, its experimental device and control method. This method can effectively and accurately fill the titanium alloy with a certain amount of hydrogen needed for the study. This paper also studied the titanium alloy in high temperature tensile test and superplasticity test, the sample hydrogen retention method, and introduced the test device.
