| Abstract |
In order to develop mechanically alloyed nano-sized ferritic ODS alloys, we have investigated the effect of three kinds of oxide such as Y₂O₃, Al₂O₃ and TiO₂, on the high temperature tensile properties, high temperature oxidation behavior and corrosion resistance. Due to the most distribution of fine and spherical particles, ODS alloys containing Y₂O₃ raise yield strength and tensile strength at high temperatures considerably. The results of high temperature oxidation tests indicate that the ODS alloys containing Y₂O₃, Al₂O₃ and TiO₂ are resistant to oxidation between 823K and 1023K. The ODS alloy containing Y2O3 by attributed by to thermal safety of Y₂O₃ showed an ecellent characteristics in oxidation and corrosion. |
