Furthermore, the AlNb2 second phase is formed and increases gradually with increasing x from 0.02 to 0.1. The lattice parameters, cell volume decrease abnormally with increasing x from 0 to 0.02 and then increase gradually when x increases further.

• 结果表明:所有合金均仍主要由斜六面体PuNi_3型的(La；Mg)Ni_3相和六方CaCu_5型的LaNi_5相所组成；当x=0.；02-0
