發(fā)布時間:2018-11-05 18:41
【摘要】:采用粉末冶金法制備了Cu-FeC復(fù)合材料,并進(jìn)行了淬火與時效處理。采用金相顯微鏡(OM)、掃描電子顯微鏡(SEM)表征了Cu-FeC復(fù)合材料的組織形貌,并對其密度、導(dǎo)電率和硬度進(jìn)行了測試。結(jié)果表明,隨著FeC含量的增加,Cu-FeC復(fù)合材料組織中的富鐵相逐漸增多,高碳相主要伴隨富鐵相析出,致密度逐漸增大,硬度顯著升高,但導(dǎo)電性能大幅降低;熱處理后,Cu-FeC復(fù)合材料中灰色富鐵相上析出大量彌散分布的黑色球狀高碳沉淀相,復(fù)合材料導(dǎo)電率、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.
