摘要(Abstract)：

采用机械合金化制备了Al_(70)Ni_(17)Ti_(13)非晶粉末,在450℃下采用无压烧结—热压工艺烧结制备了铝基复合材料,研究了不同含量的非晶粉末的加入对纯铝基复合材料显微组织及力学性能的影响。结果表明:复合材料的硬度随着增强体含量的增加逐渐增加,但其抗拉强度随着增强体含量的增加呈现出先上升后下降的趋势。复合材料的显微硬度由纯铝的46 HV0.01提高到195.3 HV0.01,效果显著。当非晶粉末颗粒体积分数为10%时,抗拉强度达到最大值为196.6 MPa,相比纯铝抗拉强度性能提升了113%。当非晶粉末颗粒体积分数为15%时,复合材料的耐蚀性能最佳。
