摘要:
以Al-6Cu-0.2Mg-1Mn合金为基体,采用混合盐原位反应法制备不同TiB2颗粒含量(质量分数分别为1%、3%、5%)的颗粒增强铝基复合材料,对不同处理状态的TiB2颗粒增强复合材料及Al-6Cu-0.2Mg-1Mn合金的相结构与显微组织进行分析,并测试其维氏硬度。结果表明,原位反应生成的TiB2颗粒能改善基体组织,阻止基体晶粒生长的方向性,得到等轴晶; 随着增强相TiB2颗粒含量的增加,基体组织得到明显细化; 不同处理状态3%及5%含量TiB2颗粒增强复合材料的维氏硬度均显著高于相应Al-6Cu-0.2Mg-1Mn合金的维氏硬度。
Abstract:
Metal matrix composites were fabricated in an Al-6Cu-0.2Mg-1Mn matrix reinforced by particulates of in-situ TiB2 from reaction processvia K2TiF6 and KBF4 salts in the matrix. Different percentage of TiB2,1%, 3% and 5%, respectively, was employed for the composite. Phases, microstructures and Vickers-hardness were revealed for the differently treated composites and Al-6Cu-0.2Mg-1Mn alloy. The results showed that the in-situ TiB2 particulates could improve the structure of the matrix by retarding a directional growthof the matrix grains and forming isometric grains in the matrix. A significant effect on the refinement of the grain was observed when the content of TiB2 particulates was increased. And the Vickers' hardness of the differently treated composites with 3% or 5% TiB2 was higher than that of the corresponding Al-6Cu-0.2Mg-1Mn alloys.
