摘要

选用Al-Mg二元合金

用传统的粉末冶金压制烧结方法

在单一变量的研究思路下探讨了其成形工艺路线。对于Al-5Mg合金

300MPa压制压力

600℃烧结温度

是合理的压烧参数

得到烧结件的相对密度达到95%。在此工艺参数的基础上

仿ZL303成分制备了Al-5Mg-1Si合金

其布氏硬度接近ZL303

观察了其金相显微组织

借助XRD分析了低熔点元素Zn和Sn在粉末冶金液相烧结中的作用。

Abstract

Al-Mg binary was made by conventional pressing-and-sintering techniques

and its forming parameters were approached based on single variable method. The desirable Al-Mg alloy containing 5% Mg can be successfully prepared with 300MPa pressure at 600℃ sintering temperature

whose relative density reaches 95%. Based on above mentioned processing parameters

Al-5Mg-1Si alloy similar to ZL303 alloy in components can be prepared. The hardness of the prepared alloy is approximate to that of ZL303. In addition

the microstructure of the alloy is observed by OM （optical microscope）. Meanwhile

the roles of Zn and Sn in liquid sintering system were analyzed by XRD（X-ray diffraction）.
