摘要
利用质子增强背散射 (EPBS)和X射线衍射 (XRD)等方法 ,对氘在 β相的Ti 3 2Mo 5Nb合金中的深度分布及Ti 3 2Mo 5Nb合金吸氘前后的相结构等进行了分析研究。结果表明 :该合金在低温阶段的吸氘速率明显高于纯钛 ,平均氘钛原子比高达 2 5 ,其中一部分氘与合金中的钛生成TiD1 971,另一部分氘则固溶在Ti 3 2Mo 5Nb合金中。
The depth profile of deuterium in β phase Ti 32Mo 5Nb alloy, the phase structure of alloy before and after absorbing deuterium are investigated by means of enhanced proton backscattering spectrometry and X ray diffraction, respectively. The results show that, at lower temperature, the rate of alloy absorbing deuterium is markedly higher than that in pure titanium; the mean atomic ratio of deuterium to titanium is as large as 2.5, and a portion of deuterium and titanium in Ti 32Mo 5Nb alloy forms compound TiD 1.971 and remaining portion of deuterium is dissolved in the alloy.
