摘要：

The precipitation behavior of oxide particles in mechanically alloyed powder of oxide-dispersion-strengthened steel was studied using chemical extraction method and X-ray diffraction analysis. In particular, the temperature and time dependences of the precipitation behavior of Y-Ti-O oxide particles were investigated. The results suggest more appropriate hot extrusion conditions to finely disperse oxide particles, to improve, and to guarantee the creep property of oxide-dispersion-strengthened steel.
