Superior Radiation Resistance of ZrO2-Modified W Composites

Abstract: The microstructure and mechanical properties of pure W, sintered and swaged W-1.5ZrO2 composites after 1.5 × 1015 Au+/cm2 radiation at room temperature were characterized to investigate the impact of the ZrO2 phase on the irradiation resistance mechanism of tungsten materials. It can be concluded that the ZrO2 phase near the surface consists of two irradiation damage layers, including an amorphous layer and polycrystallization regions after radiation. With the addition of the ZrO2 phase, the total density and … Show more

“…As one of rare earth oxides, Y 2 O 3 is an excellent sintering aid with a low W eutectic point of 1560 °C [ 21 ]. Therefore, it is an optimal reinforcement for oxide-dispersion-strengthened W [ 22 , 23 , 24 , 25 ]. Though Y will be oxidized for the absorption to oxygen, the formed Y 2 O 3 will not have a negative effect on the matrix.…”
