摘　　要：采用搅拌铸造法,以粉煤灰漂珠为添加物,制备出一种新型漂珠/AZ91D复合材料,研究了搅拌温度、时间和速度对复合材料组织的影响,优化了该复合材料的制备工艺。结果表明,制备参数为590℃恒温下,850 rpm搅拌5 min时,复合材料中漂珠均匀分布;漂珠的加入使基体组织细化。A novel cenospheres/AZ91D composite was prepared by addition flyash cenospheres by means of compocasting. The effects of stirring temperature, time and speed on the composites was investigated. The preparation process of the composites was also optimized. The results show that distribution of cenospheres in cenospheres/AZ91D composites is uniform under the condition of preparation parameters 590 ℃ constant temperature, 850 rpm stirring 5 min matrix microstructure was refined by cenospheres addition.
