title = "Research on improve the mechanical property by selective formation of Y-Ti-O complex oxide in Ni-based ODS alloy",
abstract = "Y2O3 is mainly applied as a dispersoid in Ni-based oxide dispersion strengthened (ODS) alloys. The added Y2O3 reacts with Ti and Al at a temperature above 1150? to form a complex oxide such as Y-Ti-O or Y-Al-O. However, previous studies have shown that Y-Al-O complex oxide has relatively coarser particles than Y-Ti-O. In this study, Ti was first added to form Y-Ti-O complex oxide, which has relatively fine particles. Subsequently, Al was added to inhibit the formation of Y-Al-O complex oxide, thus improving the high-temperature mechanical properties of ODS alloys. Ni-based ODS alloy powders with composition Ni-15CrxTi-1.1Y2O3 were mechanically alloyed using a planetary mill. Thereafter, the mechanically alloyed powders were heat treated to form a complex oxide of Y-Ti-O. A second mechanical alloying was performed by adding 4.5 wt.\% Al to the heat treated powders. The products obtained after the second alloying were sintered by SPS. The sintered specimens analyzed using a XRD, TEM and hot hardness meter.",
