| 摘 要： | 采用熔铸法制备了Al3Tip体积分数分别为4%和8%的AZ91D复合材料,研究了其显微组织和物相,测试了其致密度、硬度及磨损性能。结果表明,复合材料组织致密,原位内生的Al3Ti颗粒尺寸细小,呈球形且在基体中分布较均匀,与基体结合紧密;随Al3Ti体积分数的增加复合材料的致密度降低,硬度升高,但其耐磨性反而有所降低。与基体AZ91D合金相比,Al3Tip/AZ91D基复合材料的硬度和耐磨性均得到明显提高。

| Abstract: | Magnesium matrix composites reinforced with 4% and 8% (in volumetric fraction) Al3Ti particles were fabricated by melt casting process. Microstructure, phase constituent, relative density, hardness and wear resistance of the composites were investigated. The results reveal that dense structure in the composites can be observed, and in-situ fine and spherical Al3Ti phase is uniformly distributed into the matrix alloy with the compact bonding. With increasing in volumetric fraction of Al3Ti phase, relative de... |
