he structures of the oxide film have been studied for Zr-2.5Nb and Zr-1.0Nb-0.5Fe alloys. XRD analysis shows that the oxide film of Zr-2.5Nb alloy consists of monoclinic ZrO2 ((ZrO2)M) and (ZrO2)x. The oxide film of Zr-1.0Nb-0.5Fe alloy has been investigated by means of TIM. Clear grain and twin-substructure have been observed in the oxide film of Zr-1.0Nb-0.5Fe alloy.
