采用搅拌铸造工艺制备 AA6061/15%TiC (质量分数)铝基复合材料。构建一个经验公式用于预测搅拌铸造工艺参数对 AA6061/TiC 铝基复合材料极限抗拉强度的影响。采用有4因素、5水平组成的中心旋转组合设计方案来减少搅拌铸造实验次数。实验因素包括搅拌速率、搅拌时间、搅拌叶片角度和铸造温度。采用所建立的经验公式和显微组织观察分析这些因素对 AA6061/TiC 铝基复合材料极限抗拉强度的影响。分析结果表明：上述各因素均显著影响复合材料的极限抗拉强度。复合材料极限抗拉强度的变化归因于孔隙率、团簇的形成、TiC 颗粒在晶界的偏析及其在铝基体中的均匀分布。
Stir casting was used to produce AA6061/15%TiC (mass fraction) aluminum matrix composites (AMCs). An empirical relationship was developed to predict the effect of stir casting parameters on the ultimate tensile strength (UTS) of AA6061/TiC AMCs. A central composite rotatable design consisting of four factors and five levels was used to minimize the number of experiments, i.e., castings. The factors considered were stirring speed, stirring time, blade angle and casting temperature. The effect of those factors on the UTS of AA6061/TiC AMCs was derived using the developed empirical relationship and elucidated using microstructural characterization. Each factor significantly influenced the UTS. The variation in the UTS was attributed to porosity content, cluster formation, segregation of TiC particles at the grain boundaries and homogenous distribution in the aluminum matrix.
