Abstract Phase composition of pseudobinary ZrM_2 alloy (M= Ni_(1.3), Mn_(0.6), Cr_(0.25), V_(0.05)) has been revealed by means of multiphase Rietveld analysis. It is consisted of C14, C15 Laves phase, ZrN, Zr_7M_(10) and Zr_9M_(11) intermediate phase. The abundance order of phases is following. ZrM2(C15)>Zr_7M_(10)> ZrM_2(C14)>Zr_9M_(11)>ZrN. Nonstoichiometry defects existing in A sites of C15 Laves phase were also discovered. The crystal types of Zr_7M_(10) and Zr_9M_(11) are the same with that of Zr_7Ni_(10) and Zr_9Ni_(11) respectively.Correspondent: L Guanglie, Institute of Material Structure, Hangzhuo University, Hangzhuo 310028
