本文应用X射线衍射方法、全相观察及电子探针分析方法对AI-Si-Gd(0-33.33at%)三元系合金相图的室温等温截面及中间化合物的结构进行测定和研究,这对我们了解稀土元素Gd加入到Al-Si合金后的作用机理有一定的理论指导意义.
In this paper, X-ray diffraction method, all-phase observation and electron probe method were used to determine and study the isothermal cross-section of the phase diagram and the structure of the intermediate compounds of AI-Si-Gd (0-33.33at%) ternary system It is of theoretical significance for us to understand the mechanism of the addition of rare earth element Gd to Al-Si alloy.
