摘　　要：本文研究了Zr_(1-x)T_xMn_(0.6)Ni_(1.4)(T=Ti,V;x=0,0.1,0.2,0.4,0.6)合金的晶体结构和贮氢特性。这种合金的晶体结构属于Laves相的六方结构,空间群为P6_3/mmc。用Ti和V原子替代部分Zr原子后,六方结构的晶格常数变小。六方结构晶格常数的变小致使合金的氢平衡分解压随着Ti和V原子含量的增加而升高。The crystal structure and hydrogen storage properties of Zr_(1-x)T_xMn_(0.6)Ni_(1.4)(T=Ti, V;x=0, 0.1, 0.2, 0.4,0.6) alloys have been studied. These alloys belong to hexagonal struc ture of Laves phase with space group of P6_3/mmc. After Zr atoms were partically substituted by Ti or V atoms, the crystal constants have decreased and the equilibrium pressure has increased.
