摘要

采用挤压铸造法制备了Al_2O_3纤维和石墨混合增强的镁基复合材料,研究了石墨含量对新型镁基复合材料显微组织、物相组成、显微硬度和力学性能的影响,并分析了拉伸断口形貌。结果表明,增强相在镁基复合材料中随机分布,无明显团聚现象或其他冶金缺陷;随着石墨含量的增加,新材料的显微硬度、抗拉强度和断后伸长率都呈现逐渐增大的趋势。
        It prepares Al_2O_3 fiber and graphite reinforced magnesium matrix composites based on squeeze casting method, studies the effect of graphite content on the microstructure, phase composition, microhardness and mechanical properties of the new magnesium matrix composites, and analyzes the fracture morphology. The results show that the reinforcement phase are radon distribution in magnesium matrix composites, and no obvious agglomeration or other metallurgical defects. It illustrates that the increasing of graphite content, the hardness of the new magnesium matrix composites increases gradually, and both are higher than magnesium alloy without graphite addition; the increasing of graphite content in composite materials, the tensile strength and elongation of the new type magnesium matrix composites are increased gradually.
