A study has been conducted to examine the formation behavior of mixed oxide phases in some solid solution type Ni-base ODS alloys made by MA using TEM, XRD and DTA technique. The results indicate that the mixed oxied YAlO3 phase, having a hexagonal structure and termed as YAH, formed when heating Ni-20Cr-0.3Al-0.6Y2O3(mass%) alloy up to 1173 K. The nano-electron beam diffraction experiments identified that the mixed oxide was uniform in structural aspect. NiO has a facilitative effect on forming YAH type mixed oxide and the ratio of the Y2O3 to Al2O3 has a profound effect on the crystalline structure type of the mixed oxide. The YAH mixed oxide in Ni-20Cr-0.3Al-0.6Y2O3 was stable to higher temperature than that in Ni-5Al-10Y2O3-NiO alloys. The present study suggests that the formation and the stability of mixed oxides were strongly affected by the components of ODS alloys and the impurity oxygen absorbed in materials.
