| 摘 要： | 将粗铜粉和石墨粉按不同配比混合后进行机械合金化，球磨后粉末在1．5GPa下静压固化。采用扫描电镜对粉末及固化试样进行了显微组织观察，应用XRD对球磨后粉末进行相分析，测定了固化试样的密度和显微硬度。结果表明：粉末颗粒随含碳量的增加、球磨时间的延长而逐渐细化；固化试样的硬度与含碳量和球磨时间有关，硬度随含碳量的增加而降低；而当粉末球磨24h时，固化试样的硬度最高。

| Abstract: | The powder mixture consisting of Cu and graphite was separately mechanically alloyed by high energy ball milling. After milling, the powders were statically consolidated under the pressure of 1.5 GPa. The mierostrueture of the powders and the consolidated samples were investigated by a JSM-5600LV scanning electronic microscope. The phases of the meehanieally alloyed composite powders were analyzed by XRD. The density and hardness of the consolidated samples were studied. The powder partieles became finer with the inereasel of the content of C and prolongation of the milling time The hardness of the consolidated samples varied with the content of C and the milling time, it deereased with the increasing content of C and increased with the milling time which reached a maximum at 24h. |
