| 摘 要： | 本文采用酸溶法萃取铜-氧化铝系弥散强化无氧铜中氧化铝弥散相的超细颗粒,并进行X射线分析。研究了弥散强化无氧铜材料中弥散相的结构状态、颗粒大小及其分布,以及它们与材料性能之关系。通过X射线分析证实了CuAlO_2化合物的存在是弥散强化无氧化铜焊接起泡的根本原因。所有这些为改进生产工艺,提高产品质量,提供了理论根据。

| Abstract: | The ultra-fine particle of dispersion phase,Al_2O_3,in dispersion-strengthened
oxygen-free copper were extracted by acid dissolving in Cu-Al_2O_3 system.The
structure,state,particle size and its distribution,as well as the relationship between
the above factors and the material properties were studied by X-ray diffraction
analysis(XRDA).It was also testified that the weld blistering in dispersion-
strengthened oxygen-free copper is basically caused by the existence of CuAlO_2
compound.All of these provide theortetic basis for us to improve production technique
and the product quality. |
