Abstract

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．
