Abstract: ZrV 2 is prepared by arc melting and heat treatment. The phases of the alloy prepared only by arc melting and the one by both arc melting and heat treatment are analyzed according to ASTM files and the XRD spectrogram of ZrV 2 C15 type Laves phase simulated by Cerius 2.0. It is proved that the sample prepared only by arc melting includes many pha ses, and the one by both processes is single ZrV 2 phase. No solid solutions phase is seen in the latter.
