| 摘 要： | 采用单辊旋淬法制备出纳米晶CuBe合金，利用X射线衍射、扫描电镜以及电子能谱等分析方法对纳米晶铜铍合金进行结构分析，并与原始态的CuBe合金的相结构进行了对比。研究表明：合理的快速凝固工艺能使铜铍合金的晶粒尺寸达到30 nm左右，晶粒形貌发生变化，并且有类似CuBe的金属间化合物出现。由于铍原子加入到纯铜中，使得铜铍合金的固溶度扩大，在快速凝固铜合金中有大量细小弥散的第二相颗粒，有共析转变发生。

| Abstract: | Nano-crystalline beryllium-Coppery BeCu alloy is prepared by the melt-spin method. It was characterized by X-ray diffraction,scanning electron microscope and electron spectroscopy,and its structure was compared with of the original state of the alloy CuBe. Result shows that:reasonable rapid solidification technology can decrease grain size of the CuBe alloy to 30 nm around, changing the grain morphology of the alloy; something like CuBe intermetallic compounds can be found. ln Be-doped Cu, a large number of small dispersion of the second phase particles appear in the rapid solidification alloy the solid solubility of the alloy is eahanced, and eutectoid reaction happen． |
