摘要

对单辊快淬技术制备的Cu-Be合金的显微组织及时效性能进行了研究。试验通过XRD

ESEM以及TEM等材料表征手段观察了合金的显微组织

发现单辊快淬Cu-Be合金显微组织主要由面心立方结构的α固溶体、及呈小颗粒状弥散其中的不连续沉淀γ相组成

并且整个组织呈现十分细小的等轴晶粒（1

μm）

时效沉淀过程直接影响合金硬度的变化。

Abstract

Microstructure and aging hardening behavior of Cu-Be alloy prepared by rapid solidification with single roller were investigated by XRD（X-ray diffraction）

ESEM and TEM. The results show that microstructure of the Cu-Be alloy is composed of supersaturated α phase

in which a large amount of nanoscale γ transition precipitated phase can be found

and fine island-shape β phase dispersed homogeneously in the matrix

exhibiting very fine equiaxed grain with size of 1

μm. Meanwhile

the hardness of the alloy is directly related to the aging precipitation process.
