Cu-FeC复合材料组织及性能的研究
发布时间：2018-11-05 18:41
【摘要】：采用粉末冶金法制备了Cu-FeC复合材料,并进行了淬火与时效处理。采用金相显微镜(OM)、扫描电子显微镜(SEM)表征了Cu-FeC复合材料的组织形貌,并对其密度、导电率和硬度进行了测试。结果表明,随着FeC含量的增加,Cu-FeC复合材料组织中的富铁相逐渐增多,高碳相主要伴随富铁相析出,致密度逐渐增大,硬度显著升高,但导电性能大幅降低;热处理后,Cu-FeC复合材料中灰色富铁相上析出大量弥散分布的黑色球状高碳沉淀相,复合材料导电率、硬度均有所提高。
[Abstract]:Cu-FeC composites were prepared by powder metallurgy and quenched and aged. The microstructure, density, conductivity and hardness of Cu-FeC composites were characterized by (OM), scanning electron microscope (SEM). The results show that with the increase of FeC content, the iron rich phase in the microstructure of Cu-FeC composites increases gradually, the high carbon phase mainly precipitates with the iron rich phase, the density increases gradually, the hardness increases significantly, but the electrical conductivity decreases significantly. After heat treatment, a large number of black spherical high-carbon precipitated phases were precipitated from the gray iron-rich phase in the Cu-FeC composites, and the conductivity and hardness of the composites were improved.
