摘要
研究了用机械合金化（ＭＡ）的方法制备非互溶体系的ＣＵ－Ｐｂ合金粉末的机制，对ＭＡ过程中粉末的结构、组织形态的变化及Ｐｂ的分布进行跟踪分析．实验结果表明，Ｃｕ粉和Ｐｂ粉经机械合金化后可得到组织均匀、无偏析的合金粉末，为下一步的压制、烧结工艺提供了组织保障．
In this paper, the mechanic is studied that the Cu-Pb alloy powders of mutual non-dissolvement system are made by mechanical alloying in a high-energy ball mill. The structure and form of mechanical-alloyed powders and the distribution of Pb are examined and analysized by X-ray diffraction and EPMA. The results showed that the solid-solutioned Cu-Ph powders had a fine and well-distributed structure. This provides an important basis for the next pressing and sintering process.
