摘　　要：体心立方(bcc)结构的第五族金属元素V具有高的氢渗透率和力学性能,且价格比Pd金属低。在此基础上开发的V基合金膜相比纯V有较高的抗氢脆性,有望成为未来商业应用中代替Pd-Ag的合金膜材料。本文对氢分离合金膜的渗透原理、韧性-脆性转变的氢浓度以及V基合金膜的渗透性能进行了综述并对未来发展趋势进行了简单的展望。The fifth group metal element V with the body-centered cubic(bcc)structure has higher permeability,better mechanical properties and lower price than Pd metal.Due to these merits,various vanadium alloy membranes have been developed to show greater resistance to embrittlement than pure V,which are a promising alternative for existing commercial Pd-Ag alloy membranes.In this research,we presented a review for the hydrogen permeation principle,ductile-to-brittle transition hydrogen concentration and the permeability of vanadium alloy membranes and gave some perspectives about the future development.
