| 摘 要： | 第VB族（Nb、V、Ta）难熔金属与商用Pd比不但具有较高的氢渗透率而且价格低廉，成为人们青睐的新一代可替代钯的新型氢分离膜材料。为了规模化制备高通量的氢分离合金膜，研究者们对铸锭合金先进行冷轧变形以获得大尺寸平面膜，然后通过退火处理提高渗透率从而达到合金膜通量效率提升的目的。本文从合金的冷轧成形性、轧态及后续退火态组织演变以及透氢性能三方面的研究进展进行综述，分析了冷轧成膜的成分效应，阐述铸态、冷轧态和退火态的微观组织与渗透率的关系。讨论了通过轧态后续退火改善组织结构，进而开发高通量氢分离合金膜研究所面临的问题，最后对冷轧成膜及后续退火是实现低成本可规模化制备低厚度、高渗透率氢分离合金膜的前景进行展望。

| Abstract: | The VB group (Nb, V, Ta) refractory metals have higher hydrogen permeability and lower price than commercial Pd, so they have become a new generation of preferred hydrogen separation membrane materials to replace palladium. In order to prepare high flux hydrogen separation alloy film on a large scale, the ingot alloy was first cold rolled to obtain large size flat film, and then the flux efficiency of alloy film was improved by annealing treatment to improve permeability. In this paper, the research progress of cold rolling formability, rolling and subsequent annealing microstructure evolution and hydrogen permeability of alloys are reviewed, the composition effect of cold rolling film formation is analyzed, and the relationship between microstructure and permeability of cast, cold rolling and annealing alloys is described. The problems of developing high flux hydrogen separation alloy membranes by rolling subsequent annealing to improve the microstructure were discussed. Finally, the prospect of cold rolling and subsequent annealing to realize the large-scale production of low thickness and high permeability hydrogen separation alloy membranes at low cost was prospected. |
