系统研究了(Ti-Cr)_(100-x)V_x(x=30,40,50,60;Ti/Cr=0.7～0.75)合金的微结构及储氢性能。XRD及SEM分析表明,当V含量x=30时,合金中由体心立方(bcc)结构的钒基固溶体主相和微量α-Ti第二相组成;当V含量增至x=40～50时,合金为单一的bcc相;当x=60时,合金中出现了C15型Laves第二相。储氢性能测试表明,随着V含量的增加,合金的活化性能下降;室温最大吸氢量和90℃有效放氢容量均先增加后降低,并在x=50时达到最高值。合金的P-C-T曲线平台比较宽,吸放氢压力滞后均较大。当V含量x=50时,合金的综合性能相对较佳,室温最大吸氢量可达393ml·g~(-1),90℃有效放氢容量为210ml·g~(-1)。
