摘　　要：氢气作为最主要的清洁能源,在储存和运输的研究中承担它应有的使命。固态储氢由于能在较低的压力和温度下进行工作而受到国内外研究者的青睐。在理想的固态储氢合金中,立方CsCl型结构的TiFe合金以能可逆吸放氢而闻名,其容量可达1.9%(质量分数)。以TiFe基储氢合金为研究对象并结合国内外的气-固态储氢研究进展,从氢化物相的形成方面对TiFe合金的微观结构进行分析。详细解释了TiFe合金储氢的原理和缺陷以及通过例子说明了冷轧、球磨、元素替代等方法有改善合金的储氢性能的作用,最后对TiFe合金未来储氢的发展做出了预想。因此,重点是介绍TiFe储氢合金的基本知识和最新发展,这将有助于感兴趣领域的研究人员和从业者。Hydrogen, as the most important clean energy, undertakes its due mission in the research of storage and transportation. Solid-state hydrogen storage is favored by researchers at home and abroad because it can work at lower pressure and temperature. Among the ideal solid-state hydrogen storage alloys, the cubic CsCl-type TiFe alloy is known for its reversible hydrogen absorption and desorption, and its capacity can reach 1.9 wt.%. The TiFe-based hydrogen storage alloy is taken as the research object and combined with the research progress of gas-solid hydrogen storage at home and abroad, the microstructure of TiFe alloy is analyzed from the aspect of the formation of hydride phase. The principle and defects of hydrogen storage in TiFe alloys are explained in detail, and the methods such as cold rolling, ball milling, and element substitution can improve the hydrogen storage properties of alloys. Finally, the future development of hydrogen storage in TiFe alloys is predicted. Therefore, the focus of this article is to introduce the basic knowledge and recent developments of TiFe hydrogen storage alloys, which will be helpful to researchers and practitioners in the field of interest.
