Evangelos Koultoukis, Sofoklis Makridis, Daniel Fruchart, Athanasios Stubos

摘要:

采用高频感应悬浮炉,在氩气保护下,由纯元素经熔炼和再熔炼制备了含有相同类型A、B金属的Zr基AB_2-Laves相型合金。通过粉末X射线衍射(XRD)测量和SEM/EDX分析对合金进行了表征。使用高压Sievert型仪器,在20和90 ℃下记录了系统的PCI(压力-组成-等温线)测量。本研究的目的是寻找一系列具有合适性能的快速形成金属间化合物(MH)的合金,以建造MH基氢压缩机,在20 ~100 ℃之间以相同的方式工作。

英文摘要:

Zr-based AB2-Laves phase type alloys containing the same type of A and B metals, have been prepared from pure elements by melting and subsequent re-melting under argon atmosphere by using a HF-induction levitation furnace. Characterization of the alloys has resulted from powder X-Ray Diffraction (XRD) measurements and SEM/EDX analyses. Systematic PCI (Pressure-Composition-Isotherms) measurements have been recorded at 20 and 90 oC, using a high-pressure Sievert's type apparatus. The purpose of this study is to find a series of alloys promptly forming metal hydrides (MH) with suitable properties in order to build a MH-based hydrogen compressor, working in the same way between 20 and ~100 oC.
