摘　　要：采用搅拌铸造法,在纯铝中加入粉煤灰微珠颗粒作为增强体,制备铝基粉煤灰微珠复合材料。以L(934)型正交试验数据为依据,研究增强体含量和工艺参数对铝基复合材料性能的影响。结果表明,在试验条件下,制备铝基粉煤灰微珠复合材料的最佳工艺为,在700℃加入粉煤灰微珠13%,以1200r/min的速度搅拌6min。制备的铝基复合材料密度达2.2g/cm3,抗拉强度为89MPa。The effect of various parameters on aluminum matrix composite including fly ash micro-sphere particles act as reinforced phase was investigated by using stirring casting technique. According to the data of the Lg（ 3^4） orthogonal test, the optimum parameters were chosen under this experiment condition. The results showed that under the conditions of 700 ℃molten aluminum, 13 wt% fly ash micro-spheres, stirring 6 min and stirring speed 1200 r/min, the aluminum matrix composite with density 2.2 g/cm^3 and tensile strength 89 MPa could be obtained.
