摘　　要：为了解决磁性样品不能用电镜进行能谱分析,给金相图片物相标定带来的困难,本文介绍了一种基于RIR值(参比强度)的XRD(X射线粉末衍射)半定量分析方法。利用RIR值半定量相分析方法,对化学计量比为Co79Gd14V7的磁性样品分析表明合金包含三个物相,分别为Co17-xVxGd2+Co7Gd2+Co3-xVxGd,且三个物相的质量百分比约为77.7:16.7:5.6。根据该样品物相半定量分析结果 ,成功对其金相图片进行了物相标定;该方法成功解决了样品由于具有磁性不能进行扫描电镜分析,合金金相难以标定的问题。Semi-quantitative component analysis for Co79Gd14V7 alloy was developed by RIR method. The results show that the compound was contained of three phases of Co17-xVxGd2＋Co7Gd2＋Co3-xVxGd and their mass fractions ratio was about 77.7：16.7：5.6. Based on the result from semi-quantitative analysis, the micrograph was indicated. It has successfully solved the problem of micrograph indication for the magnetic alloy which can not be examined by SEM and EDS technology.
