| 摘 要： | 采用磁悬浮感应熔炼方法制备了Ti_(10)V_(83-x)Fe_6ZrMn_x(x=0、2、4、6)储氢合金,系统研究了Mn含量对合金微观结构和储氢特性的影响.XRD及SEM分析表明,无Mn合金(x=0)具有体心立方(bcc)结构的Ti-V基固溶体单相结构,而含Mn合金(x=2～6)均由bcc主相和C14型Laves第二相组成;随着Mn含量的增加,合金bcc主相的晶格常数和晶胞体积逐渐减小.储氢性能测试表明:该系列合金的吸氢动力学性能较好,在室温和4MPa初始氢压条件下,含Mn合金无需氢化孕育期就能快速吸氢;随着Mn含量的增加,合金的P-C-T放氢平台倾斜度逐渐减小,333K放氢平台压力先增后减,并在x=4达到最高;但合金的室温吸氢容量和333K有效放氢容量随Mn含量的增加而逐渐降低.

| Abstract: | Ti10V83-xFe6ZrMnx(x=0,2,4,6) hydrogen storage alloys were prepared by induction melting with magnetic levitation,and the effects of Mn content on the microstructures and hydrogen storage properties of the alloys have been investigated systematically. XRD and SEM analyses show that the Mn-free alloy with x=0 has a single Ti-V based solid solution phase with bcc structure,while other alloys with x=2-6 consist of a bcc main phase and a small fraction of C14 type laves secondary phase. The lattice parameter and... |
