TiV0.8-xCr1.2Alx合金的结构与贮氢性能 金航军1,张金龙1,葛建生1,林根文1,孟祥海1 (1.上海大学材料,上海,200072) 摘要:研究了Al对TiV0.8-xCr1.2Alx(x=0,0.05,0.1,0.15,0.2)合金的结构与贮氢性能的影响.XRD,PCT等测试研究表明:TiV0.8-xCr1.2Alx合金均为单相bcc结构,铸态时主相为树枝状晶组织;随着Al含量由0增加到6.67 at%,合金的晶格常数变大,吸氢量和放氢量减小,氢化物标准生成焓变与生成熵变增大.放氢的平台压随着Al含量的增加而线性增大.TiV0.75Cr1.2Al0.05合金最大吸氢量达3.887%(质量分数),有效吸氢量达2.288%. 关键词:贮氢性能; 相结构; Ti-V-Cr-Al合金; hydrogen storage characteristics; phase......
