| 摘 要： | 采用卷入能力强的机械搅拌法制备Zn-4.5Al-RE-Mg-Ti(ZA)合金和纳米CeO2团簇的初步混合体,然后用高能超声对卷入的CeO2颗粒团进行分散,从而得到名义质量分数1%～6%的复合材料(ZACs)。OM观察结果表明,ZACs的室温金相组织主要包括呈小岛状分布的α(Al)+β(Zn)共析组织和呈层片状分布的α+β组织。FE-SEM的结果表明,用该法制备的ZACs中纳米CeO2微粒分布均匀。

| Abstract: | The prime mixture of Zn-4.5Al-RE-Mg-Ti alloy (ZA) and nano-CeO_2 clusters was prepared by mechanical stirring method with high engulfing ability. Then the engulfed nano-CeO_2 clusters were dispersed by high-intensity ultrasonic to obtain nano-CeO_2/ZA composites (ZACs) with the nominal mass fractions of 1%-6%. The optical microscope observations show that the microstructure of ZACs at room temperature consists of island-like eutectoid structure α(Al)+β(Zn) and lamellar structure α+β. Based on the FE-SEM results, nano-CeO_2 particulates could be homogeneously distributed in the ZACs prepared by the combination stirring technology. |
