| 英文摘要 | Rapid solidification experiments have been carried out with Cu-20%Co alloy under the high-pressure gas atomization conditions. Powders containing fine dispersions of Co-rich particles were obtained. The average radius of the Co-rich particles increases with the size of powders. The Co-rich droplets are repulsed by the solid/liquid interface during solidification and Co-rich particles distribute, therefore, mainly along the grain boundaries. Because the surface energy of the Co-rich liquid is relatively higher, the Co-rich droplets nucleate inside the atomized drop. After nucleation the Co-rich droplets move towards the center of the atomized drop under the effect of the temperature gradient. The droplets motion causes the formation of the Co-poor layer on the surface of the powder. |
