| 摘 要： | 采用高能球磨法制备了SiC／Al复合粉体，研究了制备SiC／Al复合粉体的成型工艺、SiC粒度和质量分数的变化对材料机械性能的影响，SiC／Al复合材料性能研究表明，SiC／Al复合材料的硬度及抗拉强度随SiC的粒度降低和质量分数的增加而增加，当16％SiC／Al时，复合材料的硬度和抗拉强度都达到最佳值，分别为95HB和248MPa。

| Abstract: | High energy ball milling was used to preparation SiC/Al composites flakes. Researched the molding process of SiC/Al composites and the changes of grain size and the weight fraction of the SiC.It was found that with the reducing particle size and increasing of weight fraction of SiC, tensile strength of the SiC/Al composites increased. When the weight fraction of SiC in the SiC/Al composites was about 16%, the mechanical properties of SiC/Al composites about the hardness and tensile strength both got the high-point, the hardness and tensile strength was about 95HB and 248 MPa respectively. |
