摘　　要：系统研究了Ti9.6V86.4Fe4储氢合金中掺入10%(质量分数)的Ti0.9Zr0.1Mn1.5进行复合球磨对其相结构及储氢性能的影响.X射线衍射分析表明,Ti9.6V86.4Fe4铸态合金具有单一的体心立方(BCC)结构固溶体相,当添加10%的Ti0.9Zr0.1Mn1.5复合球磨后,复合物由BCC主相和C14型Laves第2相组成.扫描电子显微镜及X射线能量色散谱仪分析表明,Ti9.6V86.4Fe4合金粉颗粒表面包覆了一层Ti0.9Zr0.1Mn1.5微粒.储氢性能测试表明,Ti9.6V86.4Fe4中掺入10%的Ti0.9Zr0.1Mn1.5复合球磨后,虽然室温最大吸氢量(质量分数)从3.86%略微降低至3.61%,但其有效储氢量(质量分数)由2.01%提高到2.11%,活化性能和P-C-T曲线平台特性都得到了明显改善.The influence of composite ball-milling with 10 % （mass fraction） Ti0. 9 Zr0. 1Mn1. 5 on the phase structure and hydrogen storage properties of Ti9.6 V86.4 Fe4 alloy were investigated. X-ray diffraction analysis shows that the as-cast Ti9. 6 V86. 4 Fe4 alloy consists of single solid solution phase with body-centered cubic （BCC） structure, and the ball-milled composite （Ti9.6 V86.4 Fe4 ＋ 10% Ti0.9Zr0.1Mn1.5） has a C14 type Laves secondary phase besides the BCC main phase. Scanning electron microscopy and energy dispersive X-ray spectrometer analysis show that there is a layer of Ti0.9Zr0.1Mn1.5 particles on the surface of the composite alloy. Compared with the as-cast Ti9.6 V86.4Fe4 alloy, the effective hydrogen storage capacity of the ball-milled composite at room temperature increases from 2.01% to 2.11%, the activation behavior and P-C-T plateau characteristics are also improved, while the maximum hydrogen absorption capacity decreases from 3.86 % to 3.61%.
